Its well past the 30th of June deadline, but there are reports that the GameSpy servers for Generals & Zero Hour, Tiberium Wars & Kane's Wrath and Red Alert 3 have now been confirmed as offline. But its not the end, because as you know, the replacement has been waiting in the wings. C&C: Online is ready to take over.
C&C: Online is a community made and managed online server for Generals, Zero Hour, C&C 3, Kane’s Wrath, and Red Alert 3, allowing you to log in and continue playing online just like you could when GameSpy’s servers were still online. All information about C&C: Online can be found right here.
