Rolling Build Infrastructure Outage

In light of the various bustages/instabilities from last week, I will be performing a few sweeping system-wide changes to the build infrastructure at Mozilla Messaging.

What this means is that today, every single build host will be at least stoped+started, and possibly rebooted too.

This should not induce bustage to the Trees, but it does mean that for a certain time window, various builders will be offline, so they won't be picking up new code pushes. For this reason, it was judged safer to hold the Trees closed while this is hapenning. That's Thunderbird, Thunderbird3.0 and Sunbird.

The work will be tracked in bug 474600, where the progress of the outage will be tracked. If you notice problems with builders during that period and you think it's related to this work, add a comment there.

Also, we'll try and keep tree closure to a minimum.
