asadotzler · 1d ago
I too am in the wilderness and Starlink is my only broadband, but I was smart enough to keep my 1.5Mbps WISP connection (radio mounted 170' up one of my redwoods) so I'm still in good shape for basic communication, even some streaming and videoconferencing, though those aren't great this morning.
Also, after my Starlink terminal rebooted a few times on its own over the last hour or so, things are looking good again.
sakopov · 1d ago
Are you using something like a CradlePoint for your WISP?
galaxy_gas · 1d ago
If it 1,5 Mb and radio mount on a tower I would more guessing toward the side of PTP line of sight Link or such Mikrotik, Unifi instead of cellular cradlepoint.
esseph · 23h ago
In the US:
Ubiquiti, Cambium, probably not Tarana because that's way too expensive for a 1.5Mbps sub. Mikrotik radios are fairly rare here, but the routers and switches are everywhere.
galaxy_gas · 22h ago
Thats interesting ! Mikrotik routers and switches are very cheap, I wonder why they one product line is extremely common but the radios are rare rather than roughly equivalent spread ?
bcrl · 20h ago
Mikrotik has not (yet?) gone down the path of shipping sector radios supporting massive MIMO (Multiple Input Multiple Output -- an 8x8 array can deliver 8 times as much data as 1 stream within the same channel size) as vendors like Cambium have. The additional capacity on tower sectors from additional streams combined with MU-MIMO (Multi-User MIMO that transmits to multiple subscriber radios at the same time based on the number of streams the transmitter supports combined with client radios that are typically 2x2) is a great way to gain capacity where spectrum is exhausted. Higher order QAM support like the new 12 bits per symbol modulation in 802.11be tends not to be so useful for WISPs as getting the SNR to the level required to support it tends to be is challenging, especially in 6 GHz spectrum where transmit power limitations require much higher gain antennas for client radios (at least here in Canada where EIRP is limited to 36dBm).
Mikrotik is still quite heavily used for their routers and switches among WISPs. They are the most affordable vendor for 100Gbps switches. Pity we don't have a better open source software stack for their hardware.
Ubiquiti is also actively neglecting the WISP market. Anything that isn't UniFi seems to be mostly abandoned these days.

AdamJacobMuller · 1d ago
I broadly agree with what you're saying, but, that's not the issue here.
They don't even have a dedicated status/outage page, afaik.
The website being down is a more classic problem. The outage probably increased traffic to their website by 1000x if not more and the infrastructure for the website simply couldn't cope.
Good lesson on keeping your status infrastructure simple and on something which is highly scalable.
Having a CDN where the main page of their site was 99% cached globally would have probably mitigated this issue.

ianburrell · 1d ago
Starlink has servers for the website and subscriber sites. Importantly, they have servers for controlling the satellite network. They also have multiple gateways for satellites to connect to the network.
A problem in their network would take down the sites, and maybe the control plane for satellites.
geoffeg · 1d ago
Starlink still has infrastructure outside the satellites to run normal company stuff. If they screwed up something in their core routing system, or DNS, etc it could affect everything.

Rooster61 · 1d ago
Curious as to what could cause a global outage like that. The system consists of birds in the air and individual ground stations. There's no big choke point that I'm aware of that could cause the whole shebang to go dark. Am I missing something here?
dave_universetf · 1d ago
BGP is the canonical way to take your entire global network offline within seconds. Glancing at BGP looking glasses, Starlink's prefixes seem to still be announced, but there could still be an accidental blackhole or routing loop within their AS, or something broken in one of their transit providers.
No idea if that's what's going on, but routing protocols are one of a few effectively global control planes that can go wrong very quickly like this.
indigodaddy · 1d ago
If it were BGP/routing, you would think we'd be able to still get a signal and the modem would think it's healthy (although maybe not if the issue prevented us from obtaining our public IP), we just wouldn't be able to route to any dst. In the current case we don't have a signal (orange light on the modem)
dave_universetf · 1d ago
Does the orange light specifically mean no RF link at all? Or does it include anything that prevents the modem from getting an IP address and route configuration? If the latter, BGP could still be at fault if it took out access to the control planes on the ground. But again all just guessing, from the outside all I see is the BGP routes are still being announced, and everyone seems to be seeing 100% packet loss and zero traffic.
indigodaddy · 1d ago
Right, good point that could be the case, those were just my assumptions and probably jumping to conclusions on my part speculating that orange means no signal (don't actually have any idea :) ). Imagine it could be any of what you said too.
ta1243 · 1d ago
Yes, before the drop out my traffic was coming from a downlink station in Bulgaria, on an IP on AS14593
Traceroute from "the internet" back to that IP reaches AS14593 just fine, and my endpoint doesn't get beyond the first hop of the local starlink router.
Whatever it is, it doesn't look like a peering problem
From various monitoring points I have on multiple internet connections.
One of the promises of starlink was it would stay in space as long as possible before being downlinked, giving far lower latency, alas that hasn't happened yet, and traffic will run thousands of miles in the wrong direction before being downlinked. For example from one location to another I have 360ms via Starlink but just 200ms rtt via local provision (5g p2p wireless then optical). On another it used to downlink in Lagos, but now it downlinks in Nairobi, meaning traffic to Lagos routes Nairobi -> Marseille -> Lagos, taking far longer than it used to. A shame really.

It says it didn’t, and it says the “which way is down” thing hasn’t converged. Occasionally, the signal to noise ratio light in the app goes gray which means < 3.
It also rebooted itself.
Before the first reboot, 30% of pings went through. It’s almost like the azimuth or some other timely but cached data was corrupted.

x______________ · 19h ago
My most downvoted post by telling people to keep geopolitics out of a technical discussion. Gfy, thought you were all better.
Starlink VP of engineering Michael Nicolls tweeted that the service has "now mostly recovered from the network outage" after two and a half hours.
"The outage was due to failure of key internal software services that operate the core network. We apologize for the temporary disruption in our service; we are deeply committed to providing a highly reliable network, and will fully root cause this issue and ensure it does not occur again," the tweet, posted at 3:23 p.m. PT, says.
They still have tons of ground-based infrastructure that has all the regular failure modes. I suspect the satellites also route IP traffic statically, and they only do so to a fixed set of ground gateways all operated by Starlink (compared to e.g. Iridium, which makes in-space switching decisions and can at least continue ongoing phone calls between two devices without actually needing a reachable ground gateway).
National telcos manage to take themselves out countrywide from time to time too, so I'd assume the same usual suspects apply: Routing problems, botched global configuration changes etc.
If anything, due to centralization, ubiquitous and effectively free connectivity, and centralization/automation of configuration changes, the blast radius of any given error or malicious action has probably been steadily increasing over the years.
markasoftware · 1d ago

Almost always. Most people look at global networks like black magic and don’t realize this.
For most large businesses, 90%+ of major network events are caused by internally-driven network config changes.
Depending on how far along the business is towards automation, a proportion of the 90% can be attributed to a human going “off script” - I.e.: making a change that had not been reviewed.

They're all the same satellites. It's actually impossible to have a satellite just orbit at the poles.
There are satellites on a polar orbit, which will cover connections at the poles, but those satellites still cover a lot of non-polar ground.
If polar orbiting satellites are still working we'd expect to see intermittent or degraded connectivity away from the poles rather than complete outage?

I would still bet against the Russians taking down all of Starlink. If they had a zero day that could do that, they'd save it for just before a big war.
But Russian low-intensity hybrid warfare, including infiltration and sabotage, is very real. Particularly in Europe and especially so in eastern Europe. There's a lot of nasty things going on in border areas that isn't widely reported.
whizzter · 1d ago
Things get patched over time, Nato has their own comms systems whilst Ukraine relies on this third party, and the US just accepted the EU funded weapons sale so their Trump advantage seems to have disappeared with his patience in P's promises.
Thus using the weakness to launch a coordinated summer offensive now for a decisive breakthrough before US weapons supplies reaches full speed again seems like a reasonably good choice.
Conquering Ukraine is the key for restoring the USSR, Belarus is already under the yoke and Khz,etc won't dare resist after Ukr falls. P sees a victory here as moving the linchpin that makes him immortal in historybooks.

Ensure Starlink hires an agent. Establish skills / access permissions. Push an update which bricks both the update system and the running system, so the satellites become useless.

Spin would be indeed the most problematic, but the Starlink satellites only have krypton hall thrusters. Very efficient but also very low thrust - you you could not actually significantly waste fuel this way even if you wanted to.

You'd need to have actual knowledge of the hardware systems and serious access to do anything interesting with thrusters. It may be possible. But just bricking the updates is likely way simpler and less protected.

First you'd have to extract the documentation which may not be available to everyone. I'm just saying that in limited time, the purely software side of starlink is likely much less protected from both access and changes than anything to do with thrusters usage.

modeless · 1d ago
It's essentially impossible for anyone to disable the Starlink network by "taking out satellites" through physical means. There aren't enough anti satellite missiles in the world to make a dent, it would cost trillions to manufacture enough, and SpaceX can launch satellites faster than anyone could manufacture interceptors anyway. And Kessler syndrome is impossible at the altitudes Starlink uses.
Cyberattack is the only plausible way to take down Starlink.
gmiller123456 · 1d ago
The anti-satellite devices could be deployed in the same manner as the Starlink satellites. And they wouldn't need communications equipment, so they could be lighter and cheaper to launch. And you really wouldn't need to take them all out, just enough to make communication unreliable.
Starlink launches reduce costs by launching a bunch of satellites with similar orbits on the same vehicle, replacing one or a few satellites is going to cost a lot more per satellite. So just disrupting the network is a lot cheaper than fixing it.
Thought the cheapest is still probably paying an existing employee to break some stuff.
modeless · 1d ago
Taking out one or even a few dozen satellites isn't going to make communication unreliable. They can redistribute themselves to fill holes. You'd need to take out thousands, requiring hundreds of launches at least. And neither Russia nor China has reusable rockets, so the costs would be much higher than SpaceX's costs. The interceptors would take a long time to spread out to reach their targets if they were launched in groups like Starlink is, so it wouldn't be a surprise attack and SpaceX would have time to prepare. They would need to start launching on-orbit spares for each orbital shell, but there are only a few shells, not hundreds.
And in a few years when Starship is launching Starlink, the economics will be tilted even more wildly in SpaceX's favor.
ponector · 1d ago

Few big nukes are enough to take out all satellites.
xoa · 1d ago
>Few big nukes are enough to take out all satellites.
Um, no. Not even vaguely remotely. "Thousands of satellites" is a lot by historical human space standards, but compare that to the number of cars you see every day and then remember these are spread out over an area bigger then the surface of the entire planet. Don't be fooled by the simulation maps you can find online, where the satellites and tracks are shown thousands of times bigger then they would be to scale because otherwise they couldn't be seen. They are very, very far apart. Even on the ground, "a few big nukes" wouldn't do diddly. And nukes do less, not more, damage in space. A lot of the damage enhancement effects of nukes comes from their interaction with atmosphere. In a vacuum, it's only direct radiation which falls by the square of the distance, and satellites are of course designed to handle plenty of thermal and ionizing radiation all the time already by virtue of being designed for space. But Starlink sats aren't so high that Kessler syndrome is a concern either, there's plenty of atmospheric drag to bring debris down without active boosting.
GP is correct and I don't understand the downvotes: as far as physical resilience goes the Starlink constellation is a pretty damn hard target on an absolute basis, even before we get into the geopolitics of some country trying to shoot down US property that is also a US strategic asset.
baq · 1d ago
> Starfish Prime caused an electromagnetic pulse (EMP) that was far larger than expected, so much larger that it drove much of the instrumentation off scale, causing great difficulty in getting accurate measurements. The Starfish Prime electromagnetic pulse also made those effects known to the public by causing electrical damage in Hawaii, about 900 miles (1,450 km) away from the detonation point, knocking out about 300 streetlights, setting off numerous burglar alarms, and damaging a telephone company microwave link. The EMP damage to the microwave link shut down telephone calls from Kauai to the other Hawaiian Islands.
Yes, very good you're capable of a simplistic wikipedia search. Now I'd like you to try thinking about the paragraph you just linked for a moment: is "Hawaii", the "300 streetlights", "numerous burglar alarms", and a "microwave link" in the atmosphere (and on the ground, or indeed literally the ground) or in Earth orbit? If you read further, you'll find that the mechanism of generation involves the interaction of the gamma ray emissions with the atmosphere and Earth's magnetic field, that at 500km+ the effect are is reduced, and then find that in your example of Starfish Prime the primary damage to the satellites it affected was not due to EMP at all but rather because the test created radiation belts that damaged solar panels as satellites passed through. This would reduce design lifetime but isn't an immediate killer of everything. You'd need far more then a couple of nukes.
Of course, purposefully detonating nuclear weapons to create large scale NEMP effects might well still disrupt Starlink to the degree that it'd effect any piece of ground electronics, because the ground effects would be far, far worse. The satellite constellation could be ok enough to still be functional at reduced capacity, but if terminals and ground stations get toasted that's not immediately helpful. But that directly leads, again, to the fact that you're talking about LAUNCHING A NUCLEAR WAR ON THE ENTIRE WORLD here. No internet is going to be doing very well!
So yes: Starlink is pretty darn robust.

I wouldn't even consider a nuke for that. Energetic plasma ball resulting from nuke is not effective method to do so and any debris that survives the explosion isn't going to still be in LEO, but also no plausible deniability because it's obviously a nuke.
Try "we launched a satelite and it RUDed (honest we pinky swear it wasn't just a loose heap of ball bearings like it appears on radar) and now LEO is marginally more dangerous".

I always assumed that Starshield (DoD starlink) exists so that the DoD can make strategic geopolitical decisions (like giving satcom c&c to Ukrainian suicide drones in Crimea) without painting a target on the back of SpaceX’s big moneymaker.
They famously did not want to get involved in the war.
I imagine DoD having their own constellation with equivalent tech was the deal set up to give the Russians and whoever else a different set of targets to retaliate against, push comes to shove.
GolfPopper · 1d ago
I'm guessing the previous poster meant "a few big nukes" Starfish Prime-style, used to generate EMPs.(I don't know if Starlink satellites are protected, but my guess is they are not.)
I'm aware of the existence of the EMP weapon concept. I doubt its effectiveness against modern satellites in LEO at long range.
That very article says "The damaging effects on orbiting satellites are usually due to factors other than EMP". Also "for equipment to be affected, the weapon needs to be above the visual horizon". Given how low Starlink orbits and the fact that they are dispersed evenly over the whole Earth, the number of weapons you would need to detonate just to ensure line of sight to every satellite at a range short enough to be effective is absolutely enormous.

Nukes produce lots of gamma and x-rays. On Earth, those are absorbed to produce the fireball. In LEO, some are absorbed by upper atmosphere to make EMP. In space, they are radiation.
Except for military satellites like GPS, most satellites aren't hardened to deal with that much radiation. My guess is that the range would be thousands of miles.
oskarkk · 22h ago
I wondered how much energy could pass through some area 1000 miles away from the explosion, so I made some rough calculations.
Assumption: all energy of the nuclear explosion is radiation uniform in every direction.
The energy E would be spreading in a sphere with area 4*pi*R^2. Area A being a part of that sphere would capture E*A/(4*pi*R^2) of energy. So with:
energy E = 209 PJ (Tsar bomba for an extreme example)
area A = 1 m^2
radius of the sphere R = 1000 miles (1609 km)
So at the distance of 1000 miles an 1 m^2 object would be exposed to 6.4 kJ of radiation. I don't know how destructive would that be. That energy would be equivalent to 6 seconds of sun irradiating a 1 m^2 area above the Earth's atmosphere, but of course sun's radiation is less dangerous (very little gamma/x-ray), and all of that radiation would be almost instant.
From what I'm reading about high-altitude nuclear testing, it can cause artificial radiation belts around the Earth (composed of high-energy electrons). I think that may be more dangerous to satellites at distances like 1000 miles (or at any distance) than the immediate gamma/x-ray radiation.
ianburrell · 18h ago
Radiation is measured in gray, which is 1 J absorbed by 1 kg. I can't find the conversion between flux to absorbed dose. 5 gray is fatal. If even a fraction of that energy is absorbed, it would be fatal.
I found that satellites get 100-1000 rad per year. Getting that much in a moment would cause problems.

> Radiation is measured in gray, which is 1 J absorbed by 1 kg. I can't find the conversion between flux to absorbed dose. 5 gray is fatal. If even a fraction of that energy is absorbed, it would be fatal.
It's measured in a lot of different ways depending on the need, and the unit "sievert" is Gy times a conversion factor that depends on the kind of radiation (for equivalent dose) and which body parts (for effective dose): https://en.wikipedia.org/wiki/Sievert#Radiation_type_weighti...
But also, beta radiation (electrons) will be stopped by a thin sheet of tinfoil, while alpha radiation (helium-4 nuclei) by paper or the outer layer of dead skin on your body and therefore only matters if you eat a source of it, and a significant fraction of any gamma radiation you're exposed to will pass right through you without getting absorbed.
oskarkk · 16h ago
So, given that human body area viewed from the front is around 0.5 m^2, then a 70 kg human in space 1000 miles from the explosion would get 6.4 kJ * 0.5 / 70 kg = 45 gray. That would mean that even being a couple thousand miles away could be fatal. But that's assuming 100% of Tsar Bomba energy would be ionizing radiation, I don't know what % would that be in reality.
baq · 1d ago
digging a bit deeper, apparently most damage is coming from irradiated material interacting with solar panels of satellites passing through the cloud. sounds like it'll work, just not immediately and not necessarily via an actual EMP.
cozzyd · 17h ago
Taking out GNSS satellites would probably also effectively take out starlink.
User terminals rely on GNSS for timing and position and I wouldn't be surprised if the satellites did too.
dmonitor · 1d ago
Could some kind of microwave / laser attack from a high altitude air vehicle be possible?
shermantanktop · 1d ago
If they had that capability, they could presumably do it any time, and then Starlink would recover at some point.
So it would make sense to combine this with some other offensive action where hampering communication would help them. Otherwise they are just poking at something just to do it... unless this were a more serious attack with long-term consequences.
Yeah, Russia maanged to knock Viasat offline with hacking during the initial invasion. The original donated Starlinks were supposed to replace Viasat and SpaceX was surprised that they ended up being used on the front lines. Russia has certainly been trying to knock them out ever since.
asadotzler · 1d ago
If my memory is accurate, that didn't knock Viasat offline, it only made most of Viasat's customers unable to connect, but the network was just fine, only user routers were broken.

I imagine it is illegal for Starlink to not geofence service to prevent Russians using it for exactly that purpose. Sanctions still exist, after all.
rossdavidh · 8h ago

I'd wonder about someone targeting Musk seeing as Starlink is one of his ventures that seems to be running well up to now while his other companies have issues. Having typed that out it seems like a spy movie plot, but that seems to be the world we're living in recently.
newsclues · 1d ago
I don’t think musk himself would be the weakest link, as the high profile brings scrutiny and thus increased security and counterintelligence. Trying would be a good way to get the FBI to look into you.

Doesn’t the military use a different starlink or something ?
If not and this was a cyber attack the this an attack on the USA.
flytyer37 · 1d ago
Starlink has been supporting Russia over Ukraine (congressional investigation into this). So I would bet against Russia, but you never know. Could be rouge. Anonymous has promised in the past to mess with Musk... could be that. Well funded and some crazy good hackers.
rossdavidh · 8h ago
In terms of actual actions, Starlink has done a lot more for Ukraine than almost anyone else, since early on. Musk says stuff from time to time in order to try to keep Putin from noticing this, and pushing him out of a window or something. But his actions are that he let Ukraine use Starlink for over a year for free, and they still use it widely today.
matwood · 1d ago
Been using Starlink for awhile and can’t remember the last time there was an outage like this.

For those who refuse to use X, as we all should, this is a post from Starlink that says simply:

woutifier · 1d ago
Indeed but in this case it coincided with starlink going down. Could be a coincidence though!
indigodaddy · 1d ago
Yeah, that's interesting actually, I guess one could speculate that the fact that you got a new IP might mean they rolled out/restarted something at the application layer and then things went south from there perhaps
Scoundreller · 16h ago

ethagnawl · 1d ago
I'm not saying there's a connection to the UK telco outage but the timing is rather coincidental.
tobyjsullivan · 1d ago
Given the ongoing expansion of cellular Starlink, it could make sense.
I brought my Starlink on a three week RV trip through the western U.S., and it was pretty impressive. I was surprised it worked well even in some wooded areas. I would’ve been pretty frustrated if it had stopped working.
exiguus · 1d ago
Is this because they have now more then 50 user per square mile [1]?
Outages suck but for me this service has been rock solid. Much better uptime and more capable than the cellular broadband service that it replaced (Bell Canada) at a similar cost
Yea, my house is on Starlink... so at the moment I'm working in the back room of my wife's restaurant (she has cable internet). At least I get free coffee here.

I'm in Colorado. Starlink has worked flawlessly since I installed it 2 years ago. This is ominous.
[1] https://www.rfc-editor.org/rfc/rfc1149 [2] https://archive.google/pigeonrank/
Also, after my Starlink terminal rebooted a few times on its own over the last hour or so, things are looking good again.
Ubiquiti, Cambium, probably not Tarana because that's way too expensive for a 1.5Mbps sub. Mikrotik radios are fairly rare here, but the routers and switches are everywhere.
Mikrotik is still quite heavily used for their routers and switches among WISPs. They are the most affordable vendor for 100Gbps switches. Pity we don't have a better open source software stack for their hardware.
Ubiquiti is also actively neglecting the WISP market. Anything that isn't UniFi seems to be mostly abandoned these days.
No comments yet
They don't even have a dedicated status/outage page, afaik.
The website being down is a more classic problem. The outage probably increased traffic to their website by 1000x if not more and the infrastructure for the website simply couldn't cope.
Good lesson on keeping your status infrastructure simple and on something which is highly scalable.
Having a CDN where the main page of their site was 99% cached globally would have probably mitigated this issue.
You just hang up cuz you know it’s everyone.
A problem in their network would take down the sites, and maybe the control plane for satellites.
No idea if that's what's going on, but routing protocols are one of a few effectively global control planes that can go wrong very quickly like this.
Traceroute from "the internet" back to that IP reaches AS14593 just fine, and my endpoint doesn't get beyond the first hop of the local starlink router.
Whatever it is, it doesn't look like a peering problem
One of the promises of starlink was it would stay in space as long as possible before being downlinked, giving far lower latency, alas that hasn't happened yet, and traffic will run thousands of miles in the wrong direction before being downlinked. For example from one location to another I have 360ms via Starlink but just 200ms rtt via local provision (5g p2p wireless then optical). On another it used to downlink in Lagos, but now it downlinks in Nairobi, meaning traffic to Lagos routes Nairobi -> Marseille -> Lagos, taking far longer than it used to. A shame really.
Whoever is doing immediate global deployments and/or any prod deployments without verified testing is just wrong as a corporate culture.
But hey, if you haven’t caused an incident yet, that just means you’re still in onboarding. Those SLA downtime budgets are there to be spent.
It says it didn’t, and it says the “which way is down” thing hasn’t converged. Occasionally, the signal to noise ratio light in the app goes gray which means < 3.
It also rebooted itself.
Before the first reboot, 30% of pings went through. It’s almost like the azimuth or some other timely but cached data was corrupted.
It's not like you can have a tech go out and reboot it or reinstall windows.
Here's a great talk on roughly this topic: https://media.ccc.de/v/38c3-hacking-yourself-a-satellite-rec...
If anyone has benefited humanity over the last couple of decades, it's Elon Musk! I'd argue he's done more than anyone!
This is hybrid warfare, not a coincidence.
Russia needs to learn some manners, the hard way.
And of course, they have to downvote to hell. They need to keep the illusion that the US is still the most powerful military, the most powerful economy, and that AI will save their hegemony.
Really sad.
What is the illusion is that a powerful military is enough to win a conflict.
Other social media networks may tolerate this but this is not HN worthy.
Edit: funny, can't even access the replies..
National telcos manage to take themselves out countrywide from time to time too, so I'd assume the same usual suspects apply: Routing problems, botched global configuration changes etc.
If anything, due to centralization, ubiquitous and effectively free connectivity, and centralization/automation of configuration changes, the blast radius of any given error or malicious action has probably been steadily increasing over the years.
For most large businesses, 90%+ of major network events are caused by internally-driven network config changes.
Depending on how far along the business is towards automation, a proportion of the 90% can be attributed to a human going “off script” - I.e.: making a change that had not been reviewed.
Additional points for a user to cause the loop by plugging an rj-45 where they weren't supposed to, despite no warning or label telling them not to!
I love when devs talk about networking.
Heh.
You would expect to be able to at least connect to a satellite unless the satellite has no Internet connection so it does not make itself available to be connected to you.
Anyone have any deeper knowledge about this for the curious?
[1] https://www.pcmag.com/news/spacexs-starlink-hit-by-major-out...
But thanks for the link anyway.
There are satellites on a polar orbit, which will cover connections at the poles, but those satellites still cover a lot of non-polar ground.
If polar orbiting satellites are still working we'd expect to see intermittent or degraded connectivity away from the poles rather than complete outage?
Edit: Wow, that’s the fastest any of my HN posts have ever been buried. Still, as an old guy, I have to say it’s pretty awesome to be living in a future where polar satellites can keep someone in touch with the rest of civilization.
No idea if this is plausible at all, just raising the question for anyone who knows more about this system than I do.
But Russian low-intensity hybrid warfare, including infiltration and sabotage, is very real. Particularly in Europe and especially so in eastern Europe. There's a lot of nasty things going on in border areas that isn't widely reported.
Thus using the weakness to launch a coordinated summer offensive now for a decisive breakthrough before US weapons supplies reaches full speed again seems like a reasonably good choice.
Conquering Ukraine is the key for restoring the USSR, Belarus is already under the yoke and Khz,etc won't dare resist after Ukr falls. P sees a victory here as moving the linchpin that makes him immortal in historybooks.

Ensure Starlink hires an agent. Establish skills / access permissions. Push an update which bricks both the update system and the running system, so the satellites become useless.
Potentially you could burn the constellation with reentry.
Just put them into a spin with a strong propellant burn while compromising ground stations. Even if the fleet recovers, its lifespan will have been significantly reduced by the propellant expenditure.
The agent getting the right access or finding the right people on the inside and exploiting them successfully without trigger counterintelligence is the hard part.
If you can get schematics or source code, you can put it to use as well.
And then you can also use communications logs and HR to find other human targets.
Cyberattack is the only plausible way to take down Starlink.
Starlink launches reduce costs by launching a bunch of satellites with similar orbits on the same vehicle, replacing one or a few satellites is going to cost a lot more per satellite. So just disrupting the network is a lot cheaper than fixing it.
Thought the cheapest is still probably paying an existing employee to break some stuff.
And in a few years when Starship is launching Starlink, the economics will be tilted even more wildly in SpaceX's favor.
Few big nukes are enough to take out all satellites.
Um, no. Not even vaguely remotely. "Thousands of satellites" is a lot by historical human space standards, but compare that to the number of cars you see every day and then remember these are spread out over an area bigger then the surface of the entire planet. Don't be fooled by the simulation maps you can find online, where the satellites and tracks are shown thousands of times bigger then they would be to scale because otherwise they couldn't be seen. They are very, very far apart. Even on the ground, "a few big nukes" wouldn't do diddly. And nukes do less, not more, damage in space. A lot of the damage enhancement effects of nukes comes from their interaction with atmosphere. In a vacuum, it's only direct radiation which falls by the square of the distance, and satellites are of course designed to handle plenty of thermal and ionizing radiation all the time already by virtue of being designed for space. But Starlink sats aren't so high that Kessler syndrome is a concern either, there's plenty of atmospheric drag to bring debris down without active boosting.
GP is correct and I don't understand the downvotes: as far as physical resilience goes the Starlink constellation is a pretty damn hard target on an absolute basis, even before we get into the geopolitics of some country trying to shoot down US property that is also a US strategic asset.
https://en.wikipedia.org/wiki/Starfish_Prime
Of course, purposefully detonating nuclear weapons to create large scale NEMP effects might well still disrupt Starlink to the degree that it'd effect any piece of ground electronics, because the ground effects would be far, far worse. The satellite constellation could be ok enough to still be functional at reduced capacity, but if terminals and ground stations get toasted that's not immediately helpful. But that directly leads, again, to the fact that you're talking about LAUNCHING A NUCLEAR WAR ON THE ENTIRE WORLD here. No internet is going to be doing very well!
So yes: Starlink is pretty darn robust.
not saying it isn't. I was the evangelist of it in 2022 and seen the pentagon salivating at what they've seen and rightly so.
what it isn't is indestructible, though - and we don't know the capability of nukes designed specifcally to cause the Kessler syndrome in LEO for a few years. if I was China I'd have a project for this commissioned by Jan 2023.
I wouldn't even consider a nuke for that. Energetic plasma ball resulting from nuke is not effective method to do so and any debris that survives the explosion isn't going to still be in LEO, but also no plausible deniability because it's obviously a nuke.
Try "we launched a satelite and it RUDed (honest we pinky swear it wasn't just a loose heap of ball bearings like it appears on radar) and now LEO is marginally more dangerous".
They famously did not want to get involved in the war.
I imagine DoD having their own constellation with equivalent tech was the deal set up to give the Russians and whoever else a different set of targets to retaliate against, push comes to shove.
https://en.wikipedia.org/wiki/Nuclear_electromagnetic_pulse
https://en.wikipedia.org/wiki/Nuclear_electromagnetic_pulse
That very article says "The damaging effects on orbiting satellites are usually due to factors other than EMP". Also "for equipment to be affected, the weapon needs to be above the visual horizon". Given how low Starlink orbits and the fact that they are dispersed evenly over the whole Earth, the number of weapons you would need to detonate just to ensure line of sight to every satellite at a range short enough to be effective is absolutely enormous.
Except for military satellites like GPS, most satellites aren't hardened to deal with that much radiation. My guess is that the range would be thousands of miles.
Assumption: all energy of the nuclear explosion is radiation uniform in every direction.
The energy E would be spreading in a sphere with area 4*pi*R^2. Area A being a part of that sphere would capture E*A/(4*pi*R^2) of energy. So with:

I think that may be more dangerous to satellites at distances like 1000 miles (or at any distance) than the immediate gamma/x-ray radiation.
I found that satellites get 100-1000 rad per year. Getting that much in a moment would cause problems.
