Considering that Avalonia (the survival island) isn't being used and that no one seems to be interested in hosting any projects there, it will be removed from the server in a month. No major structures have been built, so few players will be affected. To anyone who has chests or wants to claim materials from it, you have until April 15 to do so!
Additionally, Gondwana will be spun off on its own server, much like Rodinia is right now. This will free some of the load off the main server and make future maintenance simpler. The change will happen in the coming days and will only require a short downtime of that world; nothing will be lost during the transition, so you don't need to do anything. If you have last logged out in Gondwana, you will find yourself back in Laurasia. Just use the TransHub, as usual, to return to Keystone City and beyond!
Update: Gondwana has been successfully split up!
