Over the course of the past day, the OpenDev sysadmins performed a series of operating system upgrades for the server hosting the lists.airshipit.org, lists.opendev.org, lists.openstack.org, lists.starlingx.io, and lists.zuul-ci.org sites.
Some unexpected issues arose which we did not encounter in our earlier test upgrades, which caused the outage to run four hours longer than anticipated. Unfortunately, the server began accepting messages while we were still wrestling with a bug which may have caused some queued inbound messages to be silently dropped. If you sent a message to one of the mailing lists on these sites on September 12 between 15:00 and 00:00 UTC and don't see it appear in the list archive, it was likely lost and you should send another copy.
All mailing list sites should be back in service as of now, but if you have any questions or notice a problem we've overlooked, feel free to reply to this message, or find us in the #opendev channel on the OFTC IRC network.
