Well, I think this, in many cases, boils down to being able to pick the right provider. I mean, some providers go belly-up from time to time. Others are designed/run better. For a major provider, complete outage of all of its customers is such a big thing they'll want to avoid it always. If it happens, for a brief moment, once in five years (for example), for most companies that's an acceptable level of risk. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
