Ok this is what it says
We don't know when it will be back up.
We're looking for a hoster on which we can run it in the debugger without troubles, and that has (not required, but easier to configure...) a GUI.
We'll tell you when there's a new hoster avail. I'll take this time to continue developping 5th gen quietly (I can still put a 5th gen server up, no problem), and there's always cool servers to visit like Pokemonexperte UEPC, /tr/ocketry, Battle Island, Treehouse, Reborn server...
About the registry it won't go down, don't worry about that either.
