"More than 2 million Cox Communications broadband customers lost their connections Friday after the cable operator's Internet backbone went down, a spokesman for the Atlanta company confirmed.
"We're still investigating the root cause of the problem," Bobby Amirshahi, a Cox spokesman, told internetnews.com.
Amirshahi said the outage affected all of Cox's broadband customers -- both consumers and businesses.
In some markets, service was restored in 30 minutes, he said. However, one Cox customer in Orange County, Calif., reported that his firm's service had been dark for two hours.
Service has now been restored to all customers, Amirshahi said. The company will gather information on what caused the problem over the next few hours."
