Dear listadmins, There will be some downtime on lists.wikimedia.org tomorrow, 2021-05-19. When: 06:00 UTC, for about 30 minutes (unlikely to actually take that long). What: Emails will be queued and not delivered until maintenance finishes. The web interface will not work at this time. Why: We need to apply some database schema changes to unblock migrating the final lists: <https://phabricator.wikimedia.org/T282271> If you want to follow along we'll be in #wikimedia-operations on IRC at that time. Let us know if you have any questions. Please also forward/cross-post this message as needed. Thanks, -- Kunal
