> What was that saying? Each nine of reliability doubles the cost or some such? I don't know but if there's a domain where the five nines are a pipe dream it's the cloud: we've seen a shitload of major outages where this or that cloud provider had services down for hours. This blows the five nines for years, if not decades (6 minutes max downtime per year: good luck with your five nines when you've got a 300 minutes cloud downtime). The cloud is so unreliable people are now simply used to the Web not working: "Oh shit, it's down again, I'll try again later today or tomorrow". That's how bad the "x nines" expectation became because of the cloud.
