Hello,

Wikimedia is deprecating and phasing out unencrypted HTTP (https://phabricator.wikimedia.org/T238720), as part of this effort http://gitlab.wikimedia.org now listens on port 433 only. It should not cause any issue since we have always serve GitLab over HTTPS.

It might be possible that a bot or a local config relied on http:// and those unlikely case will now be broken. The change is https://gerrit.wikimedia.org/r/c/operations/puppet/+/904843 If you see any issue, please reach out on Phabricator task above.

Greetings
