In a few hours we'll be replacing the existing cloud-vps bastions with new systems running Debian Bullseye.

Because this is a DNS change, existing bastion sessions should not be interrupted. New connections will produce fingerprint warnings that will require you to update your .ssh/known_hosts. Here are the fingerprints for the new systems:

primary.bastion.wmcloud.org, eqiad1.bastion.wmcloud.org, bastion.wmcloud.org:

ED25519 key fingerprint is SHA256:QlZONtScYR4O5jGnrmKRhWVF9lJE+aReENpHXqeOL/4

secondary.bastion.wmcloud.org:

ED25519 key fingerprint is SHA256:tRgnLMmISSuByzzeX8yXWcdFKjZad8Hdy6Y7E6jgaGI

-Andrew + the WMCS team
