Looks like something isn't right... I see the announcement from Sprint with an AS path of 1239 852 11647, but it never gets past one of the routers on Sprint's network. I have no problem going through Cable and Wireless:
Yes, and the strange thing is that is just one IP address :-( 199.212.134.9... If you try 199.212.134.1 I bet you can get to it via sprint.
