I guess three nines availability is important.

Not even hitting 1 nine at the moment - https://mrshu.github.io/github-statuses/

I object!

The dashboard clearly says 89.15% uptime!

Who says nines need to be leading?

With enough precision in the time metric there are infinitely many nines!

Somewhere in 3.14159...% uptime there are as many nines as you like!

... assuming time is infinitely divisible. (Not a physicist, is that open?)

Lately, 9 out of 10 times i click on a github link to access the repo for $random_project_hosted_on_github I get a page saying that I've been rate limited. Even if it's my first click on a github link for the week.

I guess THAT page has the three nines availability.
