DCing 2 out of 3 games
If you look at my match history I have lost 2 out of the last 3 games I played (ignoring the custom one because I was testing connectivity). Was fine for the first 17 minutes both times then BAM "you have been disconnected." My provider is Comcast, area is California, and I know they suck but this just happened today so can't blame them just yet. Considering the board I am not the only one with this issue currently. Friend of mine who lives 42 miles from me was having the same issues at the same time. They have the same ISP.
Edit: Currently cannot see my own profile or the profiles of others and having issues staying connected to the forums. However every other website is working perfectly normal.
