I thought GitHub Actions (in particular; not the rest of GitHub) was always Azure, because it was initially a fork of Azure Pipelines?

GitHub as a whole, including the previously non-Azure bits, does seem flakier than a few years ago though, for sure.

It's possible that, even though the Actions part was always on Azure, migrating the other parts to Azure broke some connectivity between the pieces....

You seem to be correct. Not that much visible from the outside, but yes it seems like they always ran on Azure, from the 2018 launch. (Apologies for the disinfo, although I qualified it with the "I assume".)

Pre-launch I seem to recall using an entirely different product with the same name, that supported CUE or HCL and had a better gui editor. I think post acquisition they scrapped it for the current (and IMO) worse reskin.
