[HTCondor-users] Debian repos for HTCondor 9.x: Release file missing?

[Oliver Freyermuth <freyermuth@xxxxxxxxxxxxxxxxxx>]

Dear HTCondor repo admins,

some hours ago, our machines running Debian 11 / Bullseye and still using HTCondor 9.0 started throwing errors during "apt update":

 Ign:18 https://research.cs.wisc.edu/htcondor/repo/debian/9.0 bullseye InRelease
 Err:19 https://research.cs.wisc.edu/htcondor/repo/debian/9.0 bullseye Release
   404  Not Found [IP: 128.105.7.58 443]
 Reading package lists... Done
 E: The repository 'https://research.cs.wisc.edu/htcondor/repo/debian/9.0 bullseye Release' no longer has a Release file.

Indeed, looking at the directories at:
 https://research.cs.wisc.edu/htcondor/repo/debian/9.0/dists/
the "Release" files and other metadata are only still there for stretch and bookworm, but gone for bullseye and buster.

Is there a problem with the repositories servers?

Cheers,
	Oliver
