We’re going to upgrade the firewall in our meer.net colocation facility this evening (Friday) at 6pm PDT (Sat 1am UTC). The upgrade affects many services, including Bugzilla, Bonsai, Tinderbox, LXR, CVS, mozilla.org mail, mozillafoundation.org mail, devmo, the wikis, IRC, and the mailing lists. We expect no more than a few seconds of downtime, but we’ll work for up to an hour to resolve unexpected problems before rolling back to the current firewall, so there may be up to an hour of downtime.
If you have any problems trying to reach any mozilla.org services after the changeover has occured, try first to find us on IRC at irc.mozilla.org #bmo, or if the IRC server is unreachable, mail me at justdave@bugzilla.org (which isn’t handled on mozilla.org’s network).
