This looks cool but the issue github is dealing with is exponential usage. They're trying to 30x their capacity right now - let that sink in! Microsoft here or there, any company would be struggling under this load. And I frankly don't think that any ideology driven alternative will ever be able to provide better uptime under the same load - or any alternative period, for that matter. We're just living in times where everyone is catching up with the capabilities of agents, and it was obvious that things like this will happen 12 months ago. Good luck for your project though!
You frame the symptom as the problem though. Others seem to be attributing this to Azure migration and Copilot overhead tightly coupled to GitHub infrastructure.
I agree that any company would struggle in such case. The thing is that everyone see that GH is pushing for more agents, their Copilot thingy, and AI everywhere, while basic functionality that people relies on is constantly failing.
If you push a lot of new features but your baseline is constantly failing, then something is wrong.
