Internet issues accounted for 66 percent of the reported problems, according to Down Detector.
“Some customers are having issues with their XFINITY Internet service. We apologize & appreciate your patience while we work to fix,” tweeted Comcast at 1:36 p.m ET.
In a subsequent tweet Comcast blamed the outage on “an external network issue.”
“Internet issues should now be resolved for almost all customers. We apologize for the inconvenience & thank you for your patience,” Comcast tweeted at 3:38 p.m. ET.
