On this coming Monday, Nov 22, at 22:00 UTC (14:00 PST) we are planning to migrate the production Phabricator instance from old hardware to newer hardware. (phab1001 -> phab1004)
We are reserving a 30 minute window to switch over but expect actual user impact to be much shorter.
You should not notice much, it's not a Phabricator version or distro upgrade, it's all about moving away from old hardware.
We picked a time slot where we expect user traffic to be low.
note: The git-ssh.wikimedia.org service (git over ssh for repos on Phabricator) has been disabled a while ago already already and has been deprecated. Please use Gitlab or Gerrit for all your repo needs.

Due to unexpected problems with the phd daemon crashing after some time on the new server we had to revert.
For the moment phab1001 is again the production server as before.
We will do this again after additional debugging.
