The worst part of all this is that GitHub's CTO and VP of Engineering sent out the usual "here's what we'll do to fix things" letter to their larger customers and, without exaggeration, it boiled down to: 1) "Here's a bunch of stuff we already did!" which... clearly isn't working, and 2) "We're continuing our Azure migration." also clearly not working.

So needless to say, if you depend on GitHub for critical business operations, you need to start thinking about what a world without GitHub looks like for your business and start working your way toward that. I know my confidence in GitHub's engineering leadership is at rock bottom.

Even that doesn’t really make sense to me, unless they’ve done it in a way where everything has to move at once.

Everywhere I’ve worked, if a migration is causing this much downtime then you kill the migration or slow it down. If every change has a 10% chance of bringing the site down, you only do a change every week or two until you can work out the kinks.
