To get into more specifics, live migrations in the provider donating
resources to the OpenDev Collaboratory, on which the mailing lists
are run, caused that server instance to hang at around 04:00 UTC on
2020-12-21 and required a reboot to bring it back into service. When
it booted, the queue runners for all the mailing list sites started
successfully except the one for lists.starlingx.io, which went
unnoticed until Saul brought it to our attention in IRC at 20:30 UTC
on Monday (2021-01-04). Clark quickly identified the problem and
brought that queue runner daemon online within five minutes, at
which point all backlogged posts from that two week period were
delivered to list subscribers and recorded in the list archives.

I counted something like 57 messages for starlingx-discuss (most of
which were automated testing results) received in the minutes after
service was restored. The backlog won't be apparent when looking at
the list archives however, as the messages are recorded there with
the original dates and times they were queued, rather than when they
were ultimately delivered.
