GitLab is used only for code review, issue tracking and project management. Canonical locations for source code are still https://gitweb.torproject.org/ https://git.torproject.org/ and git-rw.torproject.org.
Now that we've fixed #18050 (moved), we can revert the fallback minimum address stability to a longer period. I suggest 6 months - the period between releases.
This will be implemented as part of #18828 (moved).
