It's almost 3:30am, was in a party chat with a friend & playing GTA V when I suddenly got disconnected. It will not let me sign back into live. Go to test connection, and it always fails at the last "Xbox Live" step, but gets past the "Internet" step. Reset both modem & router but that didn't change anything. Internet is also working fine on my PC so I know it has to do with the XBL servers, it says Xbox Live: Failed under Test Status. Matchmaking: Service Alert, everything else is up.
When can I expect to be able to sign back in and resume what I was doing? I'm still able to message my friend via Xbox.com, who is still online playing.
