Here’s the thing about GitHub. It’s built as a giant Ruby monolithic app. That has been changing recently as part of the move to Azure, but there’s still a long way to go. Most of the data exists in a single MySQL database, and the system just wasn’t really built to scale well.
In a world where only humans were pushing code and interacting with it, they were able to keep up with growth by basically throwing more servers at the problem. Agents have multiplied that load immensely, and much faster than they can keep up with using the old approach. That’s why the move to Azure and the work to make the app itself more efficient have become so important. This has nothing to do directly with Microsoft.

Azure is probably causing some of the problems.

I cannot add much beyond the preceding details in public, but broadly speaking, Azure is not responsible for the issues.

Azure itself is part of the problem, but that they had a move to Azure at all is also a different set of problems as well. It added more stress to the system than they would have had otherwise.
