Recently PS3 and PC users have been experiencing issues logging into GRID’s online service and Codemasters has now confirmed that the services are permanently shut down. On the Codemasters forums their community manager wrote, “After three years of service, 2008’s Race Driver: GRID’s online play service has been discontinued for the PS3 and PC editions of the game. This follows the decision by a third party provider to decline the offer of an extended contract to continue online play on these platforms.” This announcement came after unexpected problems with the service a few weeks ago and was unannounced unlike most other shutdowns. It was not mentioned if they would seek out another company for service, though that option seems unlikely.
Forum users are outraged and a small contingent of hardcore players are very disappointed by this development, one user was even inspired to create the forum username “cmsucksballs” (which has since been changed to “NameDeleted” by moderators). Some PC players have transitioned to using software called Tunngle to emulate the servers.
The Xbox 360 still has multiplayer support. It was not said if that service would also be discontinued soon, though its possible it uses the peer to peer network of Xbox Live which would allow it to continue indefinitely.
