This has been happening pretty much every day for a long time. Maybe this will push more people towards some decentralization. A self-hosted Gitea instance my organization has been using had exactly zero downtime in the past year. None. Same with our CI system. Yes, I know, GitHub is 10⁹⁹⁹ times larger than our puny Gitea instance, and that's why they're having issues, but why should I care when one is working, and the other one isn't?
It's not about being larger, it's about doing changes. GitHub used to be pretty stable before, when they didn't really do any (user facing) changes. It stood still in terms of features, but was also pretty stable overall.
Compared to GitHub, how often does your Gitea instance go through code changes? How many major features have been switched on in that instance during the past year without any hiccups?
