Comcast officials said Tuesday they were investigating the cause of a widespread outage that disconnected thousands of people in the Bay Area from their internet, phone and cable services Monday night.
Comcast customers reported losing their connections before 10 p.m. Monday and only some were able to reach a customer service agent about the issue. Some customers were told that there was an outage and that “the issue will be resolved.”
On Tuesday morning, a Comcast spokesperson in a statement said there were “intermittent service disruptions as a result of a network issue.” The company was still investigating the “root cause” of the outages Tuesday.
“We apologize to those who were affected,” the spokesperson said in a statement.
The spokesperson did not immediately respond to a request for information about the number of customers affected in the Bay Area.
The brunt of the outage lasted a little more than an hour. Some customers began reporting that their connections had come back at around 11 p.m.
Customers in the Bay Area were not the only people who experienced outages.
Comcast’s Xfinity customers across the United States reported nearly 54,000 outages early Tuesday, according to the outage-tracking website Downdector.
