Comcast Outage

Comcast’s cable Internet service encountered problems causing users from U.S. east coast cities unable to access the Internet.

According to Doreen Vigue, Boston-based spokeswoman for Comcast, the company’s engineers are aggressively working to fix the problem. Comcast is considered as the largest cable operator, as well as Internet service provider in the U.S. Providing cable television service, telephone service, and broadband Internet to both residential and commercial customers in 39 states.

Meanwhile, numerous Twitter postings point that a Domain Name System (DNS) server problem was the problem that occurred.

DNS converts human-friendly Internet address like “www.seedol.com” into a numeric Internet address. "Our engineers are working very aggressively to fix the problem," said Doreen Vigue, a Boston-based spokeswoman for Comcast. Twitter postings point to a DNS (domain name system) server problem.

DNS is the system that converts human-friendly Internet address like "www.pcworld.com" into a numeric Internet address, which are vital to Internet communications. If the DNS servers go down there's no way for a user's PC to address data correctly and so communication stops.
