C&C: Online is now up and running as a way to maintain multiplayer support for the Command & Conquer series after Glu Mobile cut and ran on GameSpy services (thanks Ant). Here's word

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.

Playing on our server is absolutely free, but donations to our server are always welcome and needed. Your donations go directly towards server maintenance and improvements to the C&C:Online infrastructure.
