Hi Toni,
Fuerte builds are continuing. You can see the dashboard here:
http://www.ros.org/debbuild/fuerte.html We generally hold updates in our testing repository for a little while to give them testing time before syncing them to the public repository. Your groovy release was lucky in it's timing being just before a sync. This also is done to save most users large download volumes and provide time for testing before public release.
If you want to use them from the testing repository you can edit your apt sources to use ros-shadow-fixed/ubuntu instead of ros/ubuntu to get the testing repository. Note although usually stable, the shadow-fixed repository is a testing repository and may have missing packages or no packages at all depending on the build cycle.
