iirc it's been a while they where on rackspace when Microsoft bought them out - there was an article a few months ago saying they where moving to Azure and freezing new features while they do the move[1].

Honestly I don't know half the features they have added because the surface is huge at this point everyone seems to be using a (different) subset of them anyway.

So a feature freeze isn't likely to have much impact on me.

EDIT: went and checked - https://github.blog/news-insights/github-is-moving-to-racksp... not sure if they moved again before the MS acquisition though.

In the Pragmatic Engineer podcast episode with the former CEO of Github, the latter mentioned that they had their own infra for everything. If I remember correctly, this was due to the fact that Github is quite old and at the time when Github Actions became a thing, cloud providers were not really offering the kind of infra that was necessary to support the feature.

I can't read the entirety of this article[1] because it's paywalled, but it looks like they ran their own servers:

> GitHub is currently hosted on the company’s own hardware, centrally located in Virginia

I imagine this predates their acquisition from Microsoft. Honestly, given how often Github seems to be down compared to the level of dependency people have on it, this might be one of the few cases where I might have understood if Microsoft embraced and extended a bit harder.
