Mozilla Scheduled Downtime – 12/25/2008, 7pm – 11pm PST (0300 – 0700 12/26/2008 UTC)

We’ll be taking advantage of the holiday lull and performing scheduled maintenance tonight from 7:00pm to 11:00pm PST. The following changes will take place:

  • 7:00pm PST (0300 UTC) MX change.  We’ll be updating MX records.  No downtime is expected.
  • 7:00pm PST (0300 UTC) duration 4 hours: Kernel upgrades.  We’ll be doing kernel security updates on various machines affecting the following services for approximately 10 minutes each:
  • build graphs / pageload tests
    CVS, cvs-mirror, SVN, Hg
    Despot, Doctor
    Buildbot Try Server
    MDC Search
    Internet-facing mail relays, list servers, and outbound mail (mail will be queued)
    Any sites using LDAP for authentication
    DNS/DHCP/wifi/telephone services in all Mozilla offices (except Beijing) chat server
    All database-backed websites and services, including but not limited to: Bugzilla, Breakpad, Bonsai, SUMO, SpreadFirefox, Addons, bouncer/download, Blogs, QMO, Litmus

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.

Feel free to comment directly in this blog if you see issues past the planned downtime.
