Comcast, Others Dealing With Internet Outage

Internet service for Comcast and other internet service providers appears to be out or intermittent across many parts of the U.S. on Monday afternoon.

DownDetector shows the outage affecting multiple markets across the nation. In the Denver area, internet connectivity via Comcast has been spotty. Level 3 Communications also appears to be dealing with outages Monday afternoon, according to DownDetector.

Update: DownDetector is also showing issues for ISPs that include Charter Communications, AT&T, Verizon, Microsoft Azure and RCN, as well as individual services/apps such as LinkedIn and Instagram.

The ComcastCares Twitter handle acknowledges that the MSO is dealing with a “nationwide issue.”

Some customers are having issues with their XFINITY Internet service. We apologize & appreciate your patience while we work to fix.

Comcast has been asked for further comment on Monday’s outage, though TV service and phone service appear to be up and running.

Update:  Comcast tweeted that it is monitoring an “external network issue.”

UPDATE: our teams continue to monitor an external network issue. We apologize for the inconvenience & will provide updates as we learn more.

RCN, meanwhile, said issues are stemming from “disruptions” from the Level 3 backbone and that the cable op has rerouted traffic to an alternative:

Level 3 internet backbone currently has disruptions affecting U.S. RCN immediately rerouted to alternate backbone. RCN service normal.

The disruption was caused by a configuration error. We know how important these services are to our customers. Our technicians were able to restore service within approximately 90 minutes." 

Level 3 also provided the update via Twitter:
