Certainly it would be reprehensible if the MAE-E core infrastructure (that which MFS owns/runs) wasn't backed up. However, I believe it is.
I do not believe that it is the responsibility of MFS to provide power to individual's equipment that is co-located at the site.
If reliable power is not considered an essential part of facility infrastructure, how would you suggest that tenants get it? I think that the incident at the WilTel POP in Santa Clara, CA, is sufficient to prove that having individual tenants each supply their own (typically small) UPS is a Bad Thing - the power was out long enough to drain them to zero, furthermore (this part I have second hand) some of them didn't take well to being flatlined like that. If everyone were left to solve that problem on their own ... well, imagine everyone jockeying to park their trailer-mounted portable generator near the door. Yow. Do you feel the same way about air conditioning? Security? I believe that things like power, AC, and security (all reliable) are an essential part of a facility's infrastructure (and that's why PAIX has them). When engineered on a facility-wide scale you get a stable platform on which to build up successive layers, and you get economies of scale by solving the problem once for everyone. Stephen
