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.”

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