Also, if someone were to go elsewhere seeking a flawless power supply system, how would they know that what they are getting into was really better than what they left behind? A perfect record isn't that great of a guarantee if you are trying to avoid losing one hour in five years (almost five nines), say. So I think you really have to know a lot about electrical systems and what different providers are doing before you can really be confident about what you are getting into. It is all beyond me, but the letter from the IPhouse guy made me feel like he at least knows what he is doing (I don't know them or anyone who works for them), but maybe that is true of all colo providers.
