A couple of us were in the chatroom during the DC-NY match. It was terribly slow. The lag time between sending a message and seeing it appear on the screen was around 5 minutes. FIVE MINUTES! No kidding. All of us had the same trouble and we were spread around the country on different ISPs. So this problem was not specific to certain users as far as I could tell. Any idea of why this happened?
I just tested it on a cable modem and it was fairly instant. Of course, I was the only one in the room, so who knows...
