Dear listadmins,
Please be aware for potential downtime on lists.wikimedia.org tomorrow,
2021-07-29.
When: 15:00 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: The Network Operations team performing maintenance and will bring
all network traffic to lists.wikimedia.org to a complete stop. Most
likely this will take 1 second and no one will notice, however if
something goes wrong it will take down mailing lists, hence the
notification. More technical details are available at
<https://phabricator.wikimedia.org/T286032>.
Let us know if you have any questions. Please also forward/cross-post
this message as needed.
Thanks,
-- Kunal
