Dear listadmins, Please be aware of potential downtime on lists.wikimedia.org tomorrow 2022-01-13. When: 09:00 UTC, for about 30 minutes (unlikely to take that long) What: Incoming email may not be able to reach the lists.wikimedia.org server and may need to be retried (usually automatic). Outgoing mail will be delayed until the maintenance finishes. Why: We need to apply a config change for the KVM settings for the VM running lists.wikimedia.org which requires a reboot. It will be quite brief, likely no more than five minutes, however if something goes wrong it might take longer, hence the notification. More technical details are available at https://phabricator.wikimedia.org/T294120. Let us know if you have any questions. Please also forward/cross-post this message as needed. Thanks, -- *Amir Sarabadani (he/him)* Staff Database Architect Wikimedia Foundation <https://wikimediafoundation.org/>
