(CMCSA) - Get Report

customers on the east coast experienced an Internet outage on Sunday night due to a technical glitch that has since been resolved, the company said.

At around 8:20 p.m. on Sunday night, Comcast customers in the Boston area began reporting that they had lost Internet connectivity. By 9 p.m. a number of subscribers between New Hampshire and Washington, D.C. reported that they had lost service as well.

"Internet issue not localized to Boston area, our engineers are currently working to resolve," company spokesman Will Osborne said via Twitter.

This morning the company reported that the Internet disturbance only lasted a few hours and did not affect its cable or phone services.

"Internet service continues to work properly this morning," the company said in today's statement. "It's unclear how many customers were affected. We know it was primarily located in New England/Greater Boston and DC/Beltway areas. Video and phone services were unaffected during the few hours it took engineers to restore service."

The country's biggest cable provider is still investigating the cause of the outage.

"We certainly apologize to any customers who were affected during this time," Comcast said.

Comcast shares are down more than 1.25% to just below $20.
