The servers are down again. Weird thing is we share the same internet i'm on my xbox and there working fine my son is upstairs on his xbox trying to get on live and he can't ?
Try unplugging your modem and router. turn off your console. Leave them both unplugged for 1 minute. Plug them back in, and turn back on your console. That might get it workin' again for ya.
Tried that yesterday didn't do anything we just had to wait it out.
Theyre down, once you back out, you wont get back on until theyre back up...
No chance i'm backing out then it could be hours like yesterday
