Backbone Fiber Cut Results in Outages, Comcast Says

A fiber cut at one of Comcast's backbone network providers led to video, broadband and voice outages, Comcast tweeted Friday. It believes the cut also affected other providers. The cable ISP didn't comment on questions seeking more details. CenturyLink's Level3 tweeted its network was "operating normally." Online outage tracker Outage Report showed widespread Comcast outages Friday afternoon across the Midwest and Mid-Atlantic.
