Unity Cloud Build problems (Using github)

Is Unity Cloud Build compatible with github? On the tutorials (https://unity3d.com/learn/tutorials/topics/cloud-build/your-first-cloud-build-project) is shows that git is supported, but they weren’t using github. Is github supported?

My repository is https://github.com/ChemicalDevelopment/cthulhu (with a subfolder cthulhu/ for the unity project). In the tutorial, it shows that you need to give access on bitbucket using unity’s ssh key. Is there an analogous process for github?

It looks like this is a problem with Unity Cloud Build. It was down for maintenance earlier, and I guess their log system is broken, at least for now.
