The Chicago Tribune is reporting this morning that AT&T's Voice over IP (VoIP) U-Verse service was mainly restored as of this morning, although the company says a "small number" of customers are still out.
The AP reported that the service outage, which began about 1030 EDST and was caused by a server crash, was restored to most of the 1.15 million U-verse Voice customers by 1430. AT&T wouldn't say exactly how many customers were affected or are still without service.
U-verse is available to AT&T customers in a 22-state region where AT&T has upgraded its local network to support the provision of TV services. Broadband and TV services were not affected during the outage, the Tribune story says.
U-verse Voice customers said that people trying to call them got a "non-working number" message.
