During this time we will be upgrading both the Firefox 3 and Firefox 3.1 Unit test Buildbots to a newer version (0.7.9). In order to avoid interrupting running builds we will be closing the tree at 4am PDT and stopping any new builds from being scheduled. Once all builds have finished we will perform the upgrade and open the tree again. Depending on the timing this could take anywhere from 20 minutes to a few hours. The tree should be open again no later than 7am PDT.
If there is any reason why we shouldn't go ahead with this please e-mail email@example.com
