No dog in this fight, all props to the Fly.io team for having the gumption to do what they are doing, I genuinely hope they are successful...

> It's still 99.99+% SLA

But this is simply not accurate. 99.99% uptime is < 52m 9.8s annually of downtime. They apparently blew well through that today. Looks like they essentially had the equivalent of 4 years of 99.99% uptime equivalent this evening.

Four nines is so unforgiving that it's almost the case that if people are required to be in the loop at any point during an incident, you will blow the fourth nine for the whole year in a single incident.

Again, I know it's hard. I would not want to be in the space. That fourth nine is really difficult to earn.

In the meanwhile, <hugops> to the Fly team as they work to resolve this (and hopefully get some rest).
