Quoted from DICE from ea sports:

"As you are aware from discussions on the forums, we have been having server load issues over the past few days which has affected game performance and even game stability for some players. As part of reducing server load we asked all our server hosts to shut down the EA Public servers while we work at optimizing the server browser in game to handle the large amounts of servers. Also as part of this server load cut backs, we have requested that the server providers do not put up anymore clan/rented servers either. This decision was made to reduce the impact on you guys when you are in game from affects such as slow server browser refresh, inaccurate server information refreshing and some of the other issues you have been seeing.

The server hosts can still take your orders and answer your questions but until we have made changes to keep server load down they won't be able to fill your order and put up your servers.

So you all don't worry about whether this means you can't get into a server be assured, there is enough server capacity to allow everyone to get into a server and play. It might not be your favourite server or server provider but you can still get in there and get dogtags from someone new.
Thanks for your patience and we hope to allow the hosts to put up servers again for you all as soon as possible."

Was gunna order 1 but then i stumbled across this, surely when all the server providers put all the servers back up then the problem will come back?

hopefully they will find a long term fix for this

Dont think it will stay a problem for too long. Just dont think EA were expecting such a response with this game. I think a lot of people are leaving MW2 to play BC2.
