I looked into the first test failure reported in

the size of the test log is 1.1G
There are multiple issues surrounding the problem that excessive crashes in the lab due to a product bug can bring the lab network (+ other stuff) down. issue 489845 has collected some past outages due to this, and has some ideas about what needs to be done.

bytes offloaded per job http://shortn/_iApXsTMdYc has dropped to the normal number, downgrade this to p1 and cc the current deputy.

Status: Fixed
At this point, the GS Offloader dashboard says we're back to
