  • 7:00pm PST (0300 UTC) updates. We’ll be updating to pick up code updates (bug 478960) and configuation changes (bug 475371). No downtime expected.
  • 7:30pm PST (0330 UTC) 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
    • LXR/MXR

  • 9:00pm PST (0500 UTC) CPU upgrade.  We’ll be adding a second virtual CPU to the VM.  Duration 10 minutes.

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 those bugs if you see issues past the planned downtime.
