"Things are a bit bumpy right now" – FreeBSD:15 pkg repo is essentially down

I was wondering why some of my build scripts were failing, turns out there's a pretty major event going on where the FreeBSD pkg repos for the upcoming 15.0-RELEASE are being completely rebuilt from scratch, and are thus mostly "empty".

E.g. https://pkg.freebsd.org/FreeBSD:15:amd64/latest/All/pstree-2... (404)
