I'm a bit at a loss btw where we track infra issues, sometimes there are notifications on top of https://status.nixos.org/, sometimes Hydra issues are pinned in the nixpkgs issue tracker, but I feel like it's pretty ad-hoc.
It would be nicer if there was a dedicated issue tracker for this, vs reading logs of multiple IRC channels (unless there already is one of course).
For example, 20.09 doesn't seem to have Thunderbird or Libreoffice currently, and for Thunderbird it's because of some SSH error to a builder machine: https://hydra.nixos.org/build/129301019
cole-h has joined #nixos-infra
at first glance it looks like the job just missed being built
not sure if there is a larger issue here
