My data centres have two separate supplies through two separte ups with two seperate generators, kit is striped across each one.

Of course that doesn’t help for fire/flood etc which is why we have critical workloads in two dcs.

I once worked in a building that had two separate connections to the grid which went to different substations. Their servers have more than one power supply as well so that either grid could go down. While somewhat of an outlier, it is an option if you care about this.

		That goes without saying, you still need at least one on an ups and generator though. Dual power supply services and dual supplies are or so for any important hosting environment.
