Various old links to https://bugzilla.wikipedia.org are currently showing an SSL cert error:
You attempted to reach bugzilla.wikipedia.org, but instead you
actually reached a server identifying itself as *.wikimedia.org.
This may be caused by a misconfiguration on the server or by something
more serious. An attacker on your network could be trying to get you
to visit a fake (and potentially harmful) version of
bugzilla.wikipedia.org. You should not proceed.
