I've heard that companies that run enterprise Github instances on-premises have almost equally poor availability compared to github.com. There are probably plenty of reasons why they have so many outages, though I agree one of them is probably Azure. The outages started around the same time as the number of pushed commits skyrocketed, and the number of Dependabot vulnerabilities started growing as well, which in its turn increases the amount of PRs and Actions activity. Also, LLMs regularly import dependencies that are already out of date, meaning that when doing agentic development, one commit often results in several Dependabot PRs being created instantly.
