Mozilla Scheduled Maintenance (Tree Closure) – 11/17/2010, 6am PST (1400 UTC)

RelEng will have a scheduled maintenance window Wednesday, November 17 from 6:00am to 9:00am PST.

All Firefox & TryServer trees will be closed during this window.

The following changes will take place:

  • Upgrade to buildbot0.8.2 on all the production masters. We will pick up a bunch of buildbot improvements and unblock a bunch of Fennec release automation work (bug 610045).

Apologies for the short notice but now that the upgrade has been verified in staging (yesterday), we’re trying to work within a tight deadline.

  • Thursday/Friday do not work because both Dustin & Coop, who worked on this upgrade, will be traveling.
  • Next week does not work because of scheduled Firefox releases.
  • If its not this week, we will have to wait until after U.S. Thanksgiving, which will delay some Fennec release automation work.

While this upgrade has already been tested in staging, we have a rollback plan ready in case we hit any problems in production.

If you have any reason that this downtime should not go ahead, please email release@m.c or reply on this post in dev.tree-management. Finally, if you see any problems after the downtime period ends, please file a blocker bug in
