What I was saying above is that the 'core' of a google DC has a massive amount of network interconnect and needs for battery backup not very different from a big IX point or traditional "primary CO" for a city in a telco environment. By square footage maybe 95% of a google DC might have no UPS or battery backup but the core network for things like routers and DWDM transport equipment absolutely will have such. If they were unlucky enough that the burst cooling loop met with the battery plant for the core gear in a building or small campus of buildings....
