I've got a quick question about any known issues with AT&T as an ISP. Since sometime this past August I can't get to any website that has xbox in the URL. I'm at work currently & don't know what our ISP is other than it's not AT&T. When I try to go to xbox live on my laptop it won't connect, I can connect from any PC/laptop as long as it's not an AT&T connection. Is there any known way to resolve this? AT&T says it's an xbox/microsoft issue & xbox/microsoft says it's an AT&T issue. Anybody else have this issue & what can be done to resolve it?
