Hello,
Wikimedia is deprecating and phasing out unencrypted HTTP (T238720), as part of this effort http://gerrit.wikimedia.org now yields a 403 Forbidden error.
It should not cause any issue since we have always serve Gerrit
over HTTPS and there is a header set to instruct browser to always
use that even when asking for a http:// URL. It might be possible
though 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/+/859986
If you see any issue, please poke the Phabricator task above.
