GitHub’s reliability issues started earlier than the boom in agentic coding they talk about. I have comments on here from 2025 talking about massive outages with actions and issues.
The AI boom caught them napping though, and they're slipping well into the too unreliable category
Microsoft, who invested eyewatering sums into AI, even near to betting the whole company on an AI boom, is surprised about the AI boom?
I bet it's mostly due to Azure being brittle and the AI boom is just a nice cover story (not saying it's not challenging to handle all that new load) to save face and sell more Azure services.
Microsoft management knows this. It's not like there haven't been attempts to solve these core problems. The issue is GitHub was built by exceptional engineers, and none of those people are still around.
I maintain all these problems began when they migrated off Erlang and egitd. :)
