Besides the fact that they used "99 percent" in a colloquial, informal way ... is that really how calculations like that work, or should work? I mean, if you have 99 percent availability, and 99.999 percent availability, maybe it's valid to say that the former is 1000 times worse than the other, but that could also be true by saying that 99.999 percent availability is 10,000 times worse than 99.9999999 percent availability (where a service only goes down for a third of a second in the span of a decade), and that 99.9999999 percent availability is infinity times worse than something that hasn't had an outage within whatever monitored period (since 100 percent availability is the same as ninety nine dot nine repeating availability)
