The CS team has been very active both on the CS forum and on Twitter with updates. We are continuing to monitor the realms and reported issues and are troubleshooting and fixing as quickly as possible. I understand it might be frustrating right now, but we really do have people working on it all.
We did offer free realm transfers previously, but that's no guarantee that it will resolve the high population. That said, we're keeping an eye on things should we need to consider new ones.
