99.99999% uptime is about 3 seconds of downtime per year. Yikes! Does any service on Earth have that level of uptime?

- scottlamb 6y agoNo. In some sense it doesn't matter though. There are plenty of services that have less than their claimed reliability: * They set an easy measurement that doesn't match customer experience, so they say they're in-SLO when common sense suggests otherwise. * They require customers jump through hoops to get a credit after a major incident. * The credits are often not total and/or are tiered by reliability (so you could have a 100% uptime and not give a 100% discount if you serve some errors). At the very most, they give the customer a free month. It's not as if they make the customer whole on their lost revenue. With a standard industry SLA, you can have a profitable business claiming uptime you never ever achieve.
