richtrGitHub appears to be struggling with measly three nines availability
Have anyone checked out the status page? It's actually way worse than I thought, I believe this is the first time I am actually witnessing a status page with truly horrible results.
Well then clearly you haven't taken a look at https://status.claude.com.
At that 3rd party side GH is currently noticeable worse then claude ...
Like they are down to one 9 availability and very very close to losing that to (90.2x%).
This also fit more closely to my personal experience, then the 99.900-99.989 range the article indicates...
Through honestly 99.9% means 8.76h downtime a year, if we say no more then 20min down time per 3 hours (sliding window), and no more then 1h a day, and >50% downtime being (localized) off-working hours (e.g. night, Sat,Sun) then 99.9% is something you can work with. Sure it would sometimes be slightly annoying. But should not cause any real issues.
On the other hand 90.21%... That is 35.73h outage a year. Probably still fine if for each location the working hour availability is 99.95% and the previous constraints are there. But uh, wtf. that just isn't right for a company of that size.
You may have fumbled the calculator at one point. 20Min per 3 hours is 88.8% uptime. 99.9% uptime is 11 seconds down.
