What I find problematic, especially for teams that rely on GitOps and GitHub being (relatively) stable, is the fact that GitHub's status page can't be relied on. You arrive at the conclusion, "this must be GitHub," but the status page rejects the notion, and so you go digging. That can lead to a lot of toil and wasted time, in addition to sideways looks paired with comments like, "but status shows green."
A sick person with symptoms is clearly sick, but sometimes they're asymptomatic. That's what the GitHub status page has become. When it's red and showing problems, you know you have problems. When it's all green? You know you MIGHT have problems.
That can make outages like this harder to triage, since reality is a black box.
