Well, I do know, as a customer, they are going through a large att -> 
comcast.net transition period right now.. they even left a poorly 
thought out automated message on my answering machine to let me know 
that on june 30th they plan on royally screwing up everything.. now 
naturally they didn't say that but that message sure didn't leave much 
room for any hope of contacting support that week if need be..
