Next Wednesday, December 4th, at 00:00 UTC (4pm San Francisco) there will be
a Phabricator upgrade window that might last up to 2 hours.
While we expect downtime to be much shorter than that Phabricator might be
unreachable in that time frame.
We are switching the production Phabricator server to a buster (Debian
stable) machine.
