At scale, every single one of these other platforms are going to run into the same issues except Microsoft has the money, know how, and capability of believably sorting this out at some point.

(I said "believable", not "realistically")

So the real reason GH continues to grow is that betting on GitLab just means that you'll probably run into the same problem at some point, except they aren't a hyperscaler and if even Microsoft has to span their workloads into AWS to scale, what hope can you have with smaller vendors?

Smaller users aren't likely to be persuaded to give up free GitHub Actions and larger customers are likely already using their own custom deployment. So it's a weird middle ground that doesn't have a huge market unfortunately...

Yet, companies are still choosing Github, so I don't know if all these outages have an impact. https://bloomberry.com/data/github/

Migrating off GitHub Actions is a non-trivial engineering effort. I know we've been talking for six months about "reducing our dependence" on GHA but it hasn't become a priority yet

The annoyedAtGitHub counter is so far monotonically increasing though.

So...Gitlab?

As a bonus you also get a much more sensibly designed CI system.

Gitea?

I feel like you might be my boss
