I , like most others here cannot connect to the servers. I downloaded Pingzapper and I can connect. I dont know why this would make a difference, however it is working (so far) My ISP is Charter, I I was disconnected last night like 10 PM CST.

The pingzapper thing has a free 7 days, I am not usually one to advertise an app, but its working for me, hopefully things are back to normal soon and I wont need this, but in the interim its helping (I am on PC)
