Heres an update from the ScummVM Team:

After having hosted our source code in Subversion for five years (to the day), we have today moved to the Git distributed version control system, hosted on GitHub.
The new repository page is at https://github.com/scummvm/scummvm.
For users nothing should have changed, but for developers it should now be much easier to contribute to ScummVM.
