Comcast Xfinity Internet service is down in large areas of the US due to unknown reasons, according to multiple online reports.
The issue appears to affect only the Xfinity Internet service, and not telephony or cable services.
According to DownDetector.com, a popular website where users go to report Internet problems, reports came from all over the country, with the most affected areas being Mountain View, Portland, Denver, Chicago, Seattle, New York, San Francisco, Houston, Minneapolis, and Boston.
The issue didn't affect only home users, but also business clients as well, with the outage impacting various Internet services, such as Rackspace, Microsoft Azure, and others.
Something bigs going on. I'm told like a third of the US has Comcast outages, affecting Rackspace and others.— Michael Gillespie (@demonslay335) November 6, 2017
The outage started at around 1 PM, EST. The company admitted the problem and said it's working to fix the issue. It did not provide a deadline.
Tens of thousands of users filed reports on the DownDetector website, showing the massive scale of the problem.
Some users reported slow Internet speeds, while others said Internet connectivity was down altogether.
Update: Comcast claimed on Twitter it fixed the outage, but users are still reporting connectivity issues.
