Hello,

The upgrade of stat1008 has now completed, so you can start using it again.

The SSH fingerprint of the host has changed, so you will likely receive a warning the first time you try to use it, along the lines of this:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

In our case this is to be expected. This may be followed up with a suggested ssh-keygen command to remove your old host key reference, which you may use. The new host fingerprints have been added to this page:
https://wikitech.wikimedia.org/wiki/Help:SSH_Fingerprints/stat1008.eqiad.wmnet

...so feel free to verify what you see when you next try to connect, then accept the new key.

If you have any queries or concerns, let me or anyone on the Data Platform SRE team know. Thanks.

Kind regards,
Ben

Hello,

I would like to upgrade stat1008 from buster to bullseye this Thursday at approximately 09:15 UTC.

The upgrade is expected to take up to an hour, during which time stat1008 will be unavailable for use. Work in your home directories will be left untouched, so the impact should be low, especially if you are using conda environments.

If this maintenance window is likely to cause an issue for you, please do let me know and I can look to reschedule the work. We will also be available after the upgrade, in case you experience difficulties with the upgraded operating system.

After the upgrade, stat1008 will have new SSH host fingerprints, so I will update this page SSH_Fingerprints/stat1008.eqiad.wmnet and provide some more help to get you reconnected.

Kind regards,
Ben
