responded to a widespread failure Friday that has left customers without cable, Internet and telephone services in several areas across the country. In the US, telecoms companies with more than 29 million residential and business customers, in social media, have dominated their work to restore the services to affected customers. The company did not say how many customers were affected or how long it would take to restore the service.
"One of Comcast's major backbone network partners had a fiber-optic cut that we believe affected other vendors," resident company posted on Friday afternoon on Twitter .
Fiber-optic networks transmit large amounts of Internet traffic and handle everything from online purchases to emergency calls.
A business representative did not return calls for comment.
Down Detector and Outage.Report, two websites that monitor the operation of consumer technology services, classified the system failure as extreme and published maps targeting a large number of affected customers in the metropolitan areas of New York, Philadelphia and Washington , DC as well as San Francisco, Chicago and Denver. Reports of failures, the websites said, were raised on early Friday afternoon.
Some customers used social media to discuss the outages and said they had trouble getting through the company's phones and online chats. Comcast redirected customers to an internal website on Twitter, which was also in one place and triggered a second round of customer complaints.
