Why do they go down so often? Is it true that the reason is that they've incorporated too much AI without human review?
The instability started well before vibecoding, in around 2018-2019, shortly after the Microsoft acquisition.
Microsoft has boasted 30% of their code written by AI.[1] However we could only guess if AI generated code is the issue or something else, or a combination of things.
That being said there was a noticeable trend starting around 2022.[2] That being said they’ve also been doing a big migration to Azure. It’s likely a combination of things.

GitHub had a blog post about this recently. They reported a significant uptick in volume (repos created, PRs, etc.), which they attribute to AI usage and tooling.
I personally trigger github actions approximately 50x more than I did prior to AI-driven developer coding and I'm not alone.
It could be many things. Microsoft mismanaging stuff. Azure. Vibe-coded Github. So much AI slop being committed it adds an extra burden on the servers, etc.
It's (a) they're under massively increased load because everyone's vibing up new projects these days, (b) they've been in a weird frankenstein "on azure but also we have our own control plane" state for years and they're pushing to no longer have that be the case.
I don't think vibecoding at Github has much to do with it.
