Very different trade offs in play for google who run with a relatively high tolerance for failure at the individual machine or even rack level. At one point I believe there were batteries in every rack, though I don’t know what they're building these days. A telco DC is gonna have more network interconnect with lower tolerance for failure due to capacity impact that isn’t easy to double.
Think like a fiber termination demarc vs an in-cluster mesh.

- walrus01 4y agoWhat 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....
