HN denizens are more often than not founders of exactly those companies that do need those 9's. As I wrote in my original comment: the founders are usually shocked at the thought that such a thing could happen and it definitely isn't a conscious decision that they do not have a fall-back plan. And if it was a conscious decision I'd be fine with that, but it rarely is. About as rare as companies that have in fact thought about this and whose incident recovery plans go further than 'call George to reboot the server'. You'd be surprised how many companies have not even performed the most basic risk assessment.
