In the long run, I'm not worried about host reliability. Unreliable hosts don't get paid, so they'll gradually be filtered out. As long as you avoid newbies, you shouldn't have to be terribly concerned about hosts losing your data.
I share your concerns about the whole stack being abandoned though. Perhaps the best way to guarantee long-term survival is to make your data culturally important. Then there will be a natural incentive to copy it to new formats as they arise.
