The Elite Force II community moved to a new Master server provided by a member of the community it self.
There won't be a official patch, how ever once again the community provides it self with a in-official patch. This patch edits your windows hosts file to reroute the game to the new master server.
If you are running Windows you can download and use a tool to do all the changes for you. Download: ef2_master_server_client_patch_fix.zip
For everyone else you can find the instructions to manually made the changes in our forums
You will also need the Official Patch 1.1
to play on-line (Windows only).
