NEW YORK ‚Äď‚Äď Some Internet users faced heavy delays reaching Web sites and accessing e-mail Thursday because of widespread technical troubles on WorldCom's long-haul network.
The disruptions reached beyond WorldCom customers. Its backbones carry a large portion of Internet traffic in the United States. Also, many smaller service providers use WorldCom as the primary means to connect their customers to the Internet.
WorldCom spokeswoman Jennifer Baker said the problems began about 8 a.m. She said service had been restored by afternoon.
Baker said preliminary investigations pointed to problems with the lists telling router computers how to pass data on to their destinations.
