Steam download fail

Whenever i try to download anything it says " the servers a currently too busy to handle you'r request " dont know if its steam or me or something else please help Btw The game im trying to download is Dirt 3 and modern warfare 1 again D:

Servers handling Dirt 3 are definitely being hammered by the mass of "leaked" downloads right now. You can try going to Steam>Settings>Download and setting the location to some obscure place where most people won't download.
