Comment on GitHub Outages Since Microslop Acquisition

It’s not impossible. Large reliable websites do it all the time. It’s call 100% uptime.
Sure, it’s measured per year, and sometimes they have some outage that breaks the record. But, it is possible to have 100% uptime throughout the year.

No, no website does it. There is no such thing as 100% uptime. If it happens, great, but I can guarantee you that no website even aims for 5 nines of uptime.
Google is the benchmark for website availability and in 2022 they had an outage that lasted an hour, meaning they didn’t meet 4 nines for the year.
If you miss your SLO target for the year, then you missed your SLO target. If you’re down for 60 minutes but fine for the other 11 months, 29 days and 23 hours, you still missed your yearly SLO.

In 2022. In the other years, they had 100% uptime.
Also, yes, there are plenty of clients that ask for five-nines. Is it realistic? Probably not. But, they definitely ask.
I understand how SLO targets work. If somebody is asking for a five-nines as an SLO, they are basically asking for 100% uptime, because there is no such thing as a “five minute outage”, especially not one that is fixable without total automation.
Again, a human hasn’t even gotten paged and out of bed in 5 minutes time.
