You receive no such assurances from Rackspace, OVH, Hetzner, Softlayer, etc. They could all go out of business, anybody could walk out with your data, and if you're getting DDOSed, well, as always you're getting your checkbook out to mitigate it unless you have a very large team (in which case, why are you going with a hosting company anyway?).
OP is going for the Digital Ocean of physical machines. Treat it as such. If someone wanted assurances, they're going to pay out the nose and go with an established provider.
