Hello!

GitLab will be down this coming Monday, 8th May, from 09:00 - 12:00 UTC [0].

The issue we discovered with Phabricator last week has been mitigated, so we will proceed with the datacenter switchover that was postponed on Tuesday.

Much of this switchover window will be downtime, during which you will be unable to access GitLab through ssh or the web interface.

The process will involve DNS changes and a full backup of the GitLab server in the codfw datacenter, which will then be restored on the GitLab server in the eqiad datacenter.

You can follow along on IRC in the libera.chat #wikimedia-gitlab channel[1].

Hi all,

This maintenance will be postponed, and a new date will be scheduled shortly.

During our attempt to run this maintenance today, we encountered an issue where Phabricator displays errors while Gitlab is unavailable[0]. We will be investigating this and attempting to make a fix before we attempt to migrate Gitlab again.
