A migration like this is a monumental undertaking to the level of where the only sensible way to do a migration like this is probably to not do it. I fully expect even worse reliability over the next few years before it'll get better.

#3From GitHub CTO in 2025 when they announced they're moving everything to Azure instead of letting GitHub's infrastructure remain independent:
> For us, availability is job #1, and this migration ensures GitHub remains the fast, reliable platform developers depend on
That went about as well as everyone thought back then.
Does anyone else remember back in ~2014-2015 sometime, when half the community was screaming at GitHub to "please be faster at adding more features"? I wish we could get back to platforms (or OSes for that matter) focusing in reliability and stability. Seems those days are long gone.

#4As of recently (workflows worked for months) I even have part of my CI on actions that fails with [0]
2026-02-27T10:11:51.1425380Z ##[error]The runner has received a shutdown signal. This can happen when the runner service is stopped, or a manually started runner is canceled. 2026-02-27T10:11:56.2331271Z ##[error]The operation was canceled.
I had to disable the workflows.
GitHub support response has been
“ We recommend reviewing the specific job step this occurs at to identify any areas where you can lessen parallel operations and CPU/memory consumption at one time.”
That plus other various issues makes me start to think about alternatives, and it would have never occurred to me one year back.

Re: GitHub appears to be struggling with measly three nines availability
#6Ever since Microsoft's acquisition of GitHub 8 years ago, GitHub has completely enshittified and has become so unreliable, that even self-hosting a Git repository or self-hosted actions yourself would have a far better uptime than GitHub.
This sounded crazy in 2020 when I said that in [0]. Now it doesn't in 2026 and many have realized how unreliable GitHub has become.
If there was a prediction market on the next time GitHub would have at least one major outage per week, you would be making a lot of money since it appears that AI chatbots such as Tay.ai, Zoe and Copilot are somewhat in charge of wrecking the platform.
Any other platform wouldn't tolerate such outages.

The article mentions some concerns related to migrating their MySQL clusters off bare metal.

#9I'm surprised GitHub got by acting fairly independently inside Microsoft for so long. I'm also surprised GitHub employees expected that to last
The real problem today IMO is that Microsoft waited so long to drop the charade that they now felt like they had to rip the bandaid. From what I've heard the transition hasn't gone very smoothly at all, and they've mostly been given tight deadlines with little to no help from Microsoft counterparts.

If this were a place for memes, then I'd share that swimming pool meme with Microsoft holding up copilot while GitHub is drowning.
Then Azure Dev Ops (formerly known as Visual Studio Team System) dead o n the ocean floor.
Although given how badly GitHub seems to be doing, perhaps it's better to be ignored.
