Hello,
On Tuesday 8/11/2020 at 16:00-17:00 UTC I plan to migrate the
lists.wikimedia.org mailman
service from fermium (Debian Jessie) to lists1001 (Debian Buster).
No major downtime is expected. However, delivery of messages received during this window
may be delayed until after the maintenance is complete.
The mailman major version will stay the same during this maintenance. This is an upgrade
of the underlying OS.
Please feel free to reach out with any concerns or questions (with the exception of
mailman 3 related discussion, please direct that to

Best,
