> Separate failure domains is an advantage of self-hosted.
Well the responsibility falls on the infrastructure people in an open-source project as soon as you self-host. But then again many open-source projects already do this. I'd rather have control over my repositories than host them on someone else's server which is why I'd go for self-hosted Gitlab or Gitea.
This has been my point which I have made for self-hosting over the last few months since GitHub was down on a regular basis, and going against locking in their ecosystem, which is another risk. GitLab cloud is no different. [0]
