Large swaths of the United States experienced internet connection problems today, with several major ISPs apparently affected. Comcast, Verizon, and AT&T all appeared to have issues, with Comcast blaming the outage on an “external network issue.
“This outage falls just after the one-year anniversary of a major DDOS attack on Dyn that crippled the internet for a day in October of 2016.
According to DownDetector, which tracks internet outages, Comcast customers experienced connectivity issues in “Mountain View, Denver, Portland, Chicago, Seattle, New York, San Francisco, Houston, Minneapolis, and Boston.”
There are no firm reports yet as to the cause, although some speculated that it might be some sort of attack.
