Comcast’s Xfinity landline service has been experiencing issues across the U.S. since this morning, with thousands of problems still being reported this afternoon, according to DownDetector.com. The outage map indicates that customers throughout the U.S. have encountered issues, with the most recent reports coming from San Francisco, Chicago, Portland, Mountain View, Denver, Seattle, Atlanta, Houston, New York, and Philadelphia.

The support account for Comcast’s Xfinity services tweeted Wednesday afternoon that landline phone service “customers may still be experiencing an issue with their Voice service.”

A number of customers, including businesses with Xfinity’s phone service Voice, have been tweeting that their phone lines are down with the hashtag #comcastoutage. But perhaps most troubling are emergency responder lines impacted by the massive outage. The Epping Police Department and Kingston Fire Department in New Hampshire have said their phone lines were down, and while Schuylkill County Emergency Management in Pennsylvania said it wasn’t having trouble fielding calls, it informed locals to use their mobile phones in the event of an emergency while the landlines were down.
