"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

you're best to ask the datacentre directly as any advice on here is only a guess based on what info we have.

I suspect they may have a phased power supply to allow resilience or clever power distribution....

You hear of N+1 and N+N regularly but N on its own and E don't mean much. You spell center the American way but you would expect to have 220V as well as 110v available in any reasonable DC plus multiple feeds into the building and redundancy within it and there's normally huge generators in the car park.
