I think the impact was for some reason not consistent between users (maybe due to geographical factors or maybe sharding of accounts?). We're in Asia and I think we've had three different days recently where we couldn't actually get much work done due to GitHub being flakey or down for the entire day and our CI/CD and development processes being built around it. We ended up moving off GitHub onto a self-hosted system, which took about a day of work for one engineer (CI/CD itself was already self-hosted, so just Git, issues and PRs), and there have already been two more GitHub outages since then.
