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.
I started using an agent (Codex) on my repo and it went from a a few dozen clones to thousands (3383 this week). I dunno what the agents are doing to clone the repo so many times -- I'm not running 3000 agents or prompts, maybe 10 or so this week. But if this is typical, a 1000x increase in usage across the board can't be good on the system.

agentic "ai" is going great
