Major internet outages after ‘configuration error’

Comcast’s internet service suffered massive outages on Monday across the U.S., including large metropolitan areas like New York, San Francisco and Los Angeles, due to an outage at Level 3, an internet provider to other networks.

A Level 3 spokesperson told Wired that the outages were caused by a configuration error that caused internet routing problems to major service providers like Comcast as well as Spectrum, Verizon, Cox and RCN, whose services also went down to varying degrees on Monday.

A map from Level 3 depicts the outages, which had reportedly been occurring since Monday morning showing the scale of the error, depicting internet access problems from coast to coast.

Comcast said the outages should now be resolved, but had not explained the cause. In a tweet, the telecommunications firm characterized the cause as an “external network issue.”
