Is there a reason to dismiss the question like this? It's a matter of probability: This site just appeared out of thin air as far as most of us are concerned. Yeah, Rackspace could go out of business tomorrow. But that's a hell of a lot less likely -- and more likely to happen with some sort of warning -- than a brand new provider going under (since we all know what the odds are for new businesses).

If the OP is "going for the Digital Ocean of physical machines," perhaps he should be clearer about his intentions. I personally don't think that's a reasonable assumption based on the information he's provided.
