When the outage first began, the Comcast Cares Twitter account said the company was working on a fix, while the Comcast Business account replied to angry customers, saying it appreciated their patience.
Some customers are having issues with their XFINITY Internet service. We apologize & appreciate your patience while we work to fix.

At around 2:00 p.m. Pacific time, Comcast tweeted that all customers should be back up and running.
Later in the day, a Comcast spokesperson referred us to a Techcrunch story that reported the issue actually stemmed from “backhaul” provider Level 3. The company tweeted that the problem was caused by a configuration error that affected IP-based customers like Comcast. Level 3 did not immediately respond to a request for comment.
On Nov. 6, our network experienced a disruption affecting some IP customers due to a configuration error. All are restored.
