Internet Subscribers Blocked

Cox Communications appears to be interfering with file-sharing by its Internet subscribers in the same manner that has landed Comcast Corp. in hot water with regulators, according to research obtained by The Associated Press.

A study based on the participation of 8,175 Internet users around the world found conclusive signs of blocked file-sharing connections only at three Internet service providers: Comcast and Cox in the U.S. and StarHub in Singapore.
