Bright House Networks and its owner, Time Warner, are experiencing problems with the service, preventing some customers from accessing their email.
Joe Durkin, a Bright House spokesman, said "it's a small number of customers" that have been affected for at least the last two days. He said the national Road Runner email system has been affected by the problem, which the company expected to fix by Friday afternoon.
"We apologize for this interruption," Durkin said Friday afternoon. "We anticipate this being resolved soon."
