Mozilla Scheduled Downtime – 10/07/2008, 7pm – 11pm PDT (0200 – 0600 10/08/2008 UTC)

We will have a scheduled maintenance window tonight from 7pm to 11:00pm PDT. This is being tracked in master bug 458901. The following changes will take place:

  • 7:00pm PDT (0200 UTC)* database restart and code updates. We’ll be updating to pick up code updates. We’ll also be restarting the master database to change some configuration settings. See bug 458110 for more details. This will impact and all related sub-domains. Duration 15 minutes.
  • 7:00pm PDT (0200 UTC) Final MySQL 5 migration. We will be completing our last MySQL 4 master to MySQL 5. The following services will go offline for up to 30 minutes while they are moved to a new master database:
    • Bonsai
    • Despot
    • Graph Server
    • Litmus
  • 9:00pm PDT (0200 UTC) San Jose Netscaler software upgrade. We’ll be doing a vendor recommended upgrade on the San Jose Netscalers. No downtime expected.
  • 10:00pm PDT (0200 UTC) Cisco IOS upgrade. We’ll be upgrading IOS on two of the embedded HP BladeSystem Cisco switches to pick up a bug fix (BugID CSCsf17036). The systems attached to these switches are multi-homed. No downtime expected.

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 458901. Feel free to comment directly in that bug (or this blog) if you see issues past the planned downtime.
