It is nice that they availability zones so you can get around these kinds of problems if you have the money, their outage report confirms the problem was isolated to one zone. The report also states it was a problem isolated to a group of racks, a failing power distribution unit which I take it was on the "wrong side" of the UPS. A lightning storm affected something on the "inside" of the UPS, but nothing else in the datacenter? I'm curious how that would even happen (and shouldn't a lightning rod be in use?). Also, it seems like Google's per-motherboard UPS system would have been the setup to have in order to avoid this problem in the first place.
