Comcast suffers DNS outage
Problems with the Domain Name System (DNS) servers at Internet service provider Comcast Corp. prevented customers around the U.S. from surfing the Web yesterday, but the company said the interruptions weren't linked in any way to a spate of recent DNS attacks known as "pharming" scams.
Comcast technicians noticed problems with the Philadelphia-based company's DNS servers around 6:30 p.m. EDT. The problems interrupted DNS service to Comcast high-speed Internet customers across the U.S. just hours after the SANS Institute's Internet Storm Center advised Internet service providers to make sure their DNS servers weren't vulnerable to new attacks.
