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.
http://pirateparty.org.au/ fails to load because of the "Pirate Party" rule-set and the web site not having HTTPS.
P.S. Thanks for the add-on :)
