This certainly isn't a judgement on their success---scaling to 24/7 in a month is impressive even if there remained bugs to work out. (It's also not a judgement of the OP, which explained what it set out to explain, i.e. the initial one month.) So I guess, consider this a request for an interesting follow-up post. :)
