Dear listadmins, Please be aware of potential downtime on lists.wikimedia.org next Tuesday, 2021-12-07.
When: 10:00 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 run some schema changes on the database of mailman to fix bugs mentioned in the ticket. This can't be done unless we shut down mailman software. It will be quite brief, likely no more than one minute, however if something goes wrong it might take longer, hence the notification. More technical details are available at https://phabricator.wikimedia.org/T286552. 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/>
