People from Boston to the Washington area were reporting internet outages or slow service Tuesday.
According to Downdetector.com, which tracks outages, users reported problems with Verizon, Google, Zoom, YouTube, Slack and Amazon Web Services.
Many of those services have become staples for millions of Americans working from home during the coronavirus pandemic. Students attending school virtually also depend on the services.
Verizon reported that a fiber cable in the city of New York borough of Brooklyn had been severed, but it was unclear if that was causing all the problems.
Downdetector also showed that Comcast users were reporting outages or slowdown. Comcast is a rival internet service provider.
Amazon Web Services, which provides cloud services to many companies, also reported connectivity issues, according to The Washington Post.
