• 7:00pm PDT (0200 UTC) blog/wiki database restart. We need to restart MySQL on one of our database masters to change some configuration settings. This will affect all of the sites listed below. Duration 5 minutes.
  • www.spreadfirefox.com
  • All Blogs
  • All Wikis
  • All Intranet Sites
  • All Forums
  • support.mozilla.org
  • reporter.mozilla.org
  • pastebin.mozilla.org

Please let me know if you have any reason why we should not proceed with this planned maintenance. As always, we aim to keep downtime to as little as possible, but unexpected complications can arise causing longer downtime periods than expected. All systems should be operational by the end of the maintenance window.

As mentioned, this maintenance window is tracked in bug 455896. Feel free to comment directly in that bug (or this blog) if you see issues past the planned downtime.
