Time Warner Cable subscribers across the country are experiencing service problems this morning.
The problems started at 4:30 a.m. ET, said Bobby Amirshahi, vice president of public relations for Time Warner Cable.
"During our routine network maintenance, an issue with our Internet backbone created disruption with our Internet and On Demand services," Amirshahi said in a statement.
Service was largely restored by 6 a.m., Amirshahi said, with updates ongoing to restore service to all customers.
Frustrated subscribes wrote about the situation online, making Time Warner a trending topic on Twitter.
"Nothing says good morning like a nationwide Time Warner Cable internet outage," one person wrote on Twitter.
More than 11 million residents and companies across the United States subscribe to Time Warner Cable.
