I just got home from work and decided to relax and play some modern warfare 2, when i get a response saying i cannot sign into Xbox. Alright, fine, it might be from my computer getting messed up and my switch or ethernet cable might be broken. Problem is that isn't the case because i cannot connect wireless either. I am reading about some update from yesterday/last night that might have led to me not being able to connect to Xbox live. I have gone through the support pages already and nothing has worked. So is this all on Microsoft's end?
