Hi listadmins,
There was an issue with the Mailman server following network maintenance that caused mail delivery to stop since about 2023-03-07 14:35 UTC.
It was restarted at 2023-03-09 16:02 UTC, but it will take a bit of time for it to clear through the backlog. By the time you get this email it should be all caught up.
For technical details and the forthcoming incident report, you can folow https://phabricator.wikimedia.org/T331626.
Sorry about the disruption. -- Kunal / Legoktm
