There is no lack of redundancy in powerlines. The servers all stayed up when the transformer went out. The problem is that AC units are normally not connected to the UPS, since that would increase power-draw to twice normal and result in the UPS failing in half the time. They are connected to the generators however so when outside power fails, the AC units are offlined for only ten minutes. But that is enough to melt the servers nowadays.
That and the fact that the powercircuits are not tested for failures regularly (unlike the generators) leads to problems like this. But testing the powercircuits is a very difficult thing to do. Inducing failures in loaded circuits that dissipate 200 kilowatts or more is no fun, and the transients are hell on everything connected.
