Honestly I kind of feel for them - their traffic must be spiking like no tomorrow. Though still annoying when the team takes down time because GitHub is down...has anyone transitioned to something else successfully?

I'm a DevOps freelancer and I've moved projects off GitHub Actions in prior years (cost and security driven). Everyone uses GitHub a little differently, so there isn't a single migration path. It seems like all parts of GitHub are on fire now, but I'd generally recommend moving in stages.

For my personal work I did a hard cutover to GitLab last month. The issues import is the most complex part as the default import messes up issue authors.

This makes me nostalgic for platforms like https://unfuddle.com. That was the old days of other providers with subversion and git.

It it was a startup, sure, I'd feel for them. This is Microsoft though. They have the money and resources
