I do know how to do that. I also know how to deploy bare metal servers, I have done so for years. Not really sure what you’re assuming here.
I however prefer to acknowledge the nature of the business, which is there will be an inevitable untimely failure in some way you did not prepare for despite being the most well read, well practiced and researched to the problems at hand.
There were so many severe Github Actions outages (10+ ?) in the past year. Cause: Migration to the disaster zone also known as Azure, I assume. Most of them happened during (morning) CET working hours, as to not inconvenience the americans and/or make headlines.
Money doesn't buy competency. It's a long-term culture thing. You can never let go on maintaining competency in your organization. It rots if you do. I guess Microsoft did let go.
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.
