On Friday, November 25th, we will be cutting over to new faster Internet uplinks and new firewalls in the Meer collocation facility. This is to increase security and capacity to support our core infrastructure.
The upgrade affects many services, including Bugzilla, Bonsai, Tinderbox, LXR, CVS, mozilla.org mail, mozillafoundation.org mail, Mozilla Developer Center, the wikis, IRC, the Report a Broken Website tool, and the mailing lists. We will do everything possible to minimize downtime and impact to users, but we anticipate some effect when we do the final cutover and failover testing. During the outage window, we will also be rebooting several of the servers in order to install some pending upgrades.
We will start this work at 5pm PST (1am UTC Saturday) and will be done by 7pm PST (3am UTC). Expect sporadic access to any Internet facing infrastructure during this time.
Once complete we will be performing a full suite of tests to ensure stability and functionality. We will send out an update when we have completed the work. If you see any issues relating to the upgrade after 7pm, please email sysadmins@mozilla.org or justin@mozilla.com, or comment on the #bmo channel on irc.mozilla.org.
