Regardless of what the specific technical failure might have been, and regardless of whether someone else is going to be able to step in and fix that technical failure for you, it is fairly startling that there doesn't seem to be any hint of an apology in your post or even any acknowledgement of culpability.

Would you agree that ultimately, this has almost nothing to do with the server hardware and everything to do with the decision to store private keys on a web-accessible server that is operated and maintained by somebody else, relying on a backup strategy over which you don't appear to have any direct control or direct involvement? I am not suggesting that it is never a good idea to store private keys on a web-accessible server -- obviously many services could not be operated otherwise. But I would suggest that any decision to do so ought to be undertaken with full awareness of exactly what the h*** is going on with that server, and with an absolute willingness to take full responsibility for it and everything that happens to it. From what I can tell, you have expressed neither familiarity with what is going on nor a willingness to take full responsibility for it.

Am I wrong about that?
