Not my site, and while I hear you on the backups, the perhaps more-relevant problem is the lying.
All I see in that post is hearsay and zero evidence either way of "lying". I can think of plenty of "maintenance issues" that would eventually cause a data loss - additional drives failing during a RAID rebuild, for example.
Huh? A RAID rebuild is not maintenance, and at any rate if I had a multi-site customer down hard they'd get a better explanation than that after, let's say, the second hour, especially if the ETR was unknown. Not only that, but no CEO I know of would accept this as an excuse from me if I was in charge of their company's systems.
This is basic hosting customer service, and it's the kind of service I have gotten from Rackspace in the past, though I haven't used them since they went public.
P.S. There was much more than that post in the contemporaneous tweets, that was just a convenient description. It's not just hearsay, unless you consider the person running the site to be a third-party to the issue.
If you purchased a car and got into an accident, would you also blame the manufacturer for you not having car insurance?
