Unfortunately, I don't know of any 'upstream' mirror. However, I've configured my projects to be mirrored on several locations with one easy command: git remote set-url origin --push --add <a remote> git remote set-url origin --push --add <another remote> Basically, when you `git push origin master`, it will go to both <a remote> and <another remote> at the same time. Once it's configured, there's no workflow change. I typically mirror my code with GitHub and BitBucket using this setup.
