Mozilla Scheduled Downtime - 5/25/2006, 7pm - 9pm PDT (0200 - 0400 UTC)

We will have a scheduled downtime window this coming Thursday from 7pm to 9pm PST. The following changes will take place:

* 7pm PDT - DNS architecture migration. We will be migrating our primary DNS server to a new system, setting up the current primary to slave off the new machine. We don't anticipate any downtime, but sporadic internal DNS service is possible.

Please let me know if you have any reason why we should not proceed with the planned maintenance. Feel free to email infra@mozilla.org if you see issues past the planned downtime.

Thanks,

Starting tomorrow, we will begin the migration of all Tinderboxen in Meer to virtual machines. Tinderboxen will be done in groups and expected downtime is 24 hours per group. We will keep all of the performance Tinderboxen up and running in parallel to evaluate how they run in a VM environment (argo, gaius, prometheus, pacifica, btek, creature, beast).

Please let me know if you have any reason why we should not proceed with the planned maintenance. Feel free to email infra@mozilla.org if you see issues past the planned downtime.
