AT&T Outage cause last week.
According to AT&T, in a story just released, the problem was a Cisco code problem. It would be interesting to hear what the actual software cause was, if anyone from Cisco cares to let us know?.../rlj - - - AT&T's network failure AT&T Corp. reported today that last week's frame relay network failure was due to a software-based problem. Last Monday's network failure disrupted service nationally for thousands of AT&T's business customers for about a day. The cause of the outage was previously attributed to the interaction between two frame-relay switches, but AT&T now says it was a software problem. AT&T Chairman C. Michael Armstrong said today the company is working closely with Cisco Systems, which provided its switches, on ways to fix the problem. The type of network application affected by frame-relay service is "any kind of high-speed data applications where large amounts of information [are] exchanged in quick bursts," Granieri said. Querying an inventory database is one example of such an application, he said. Reuters contributed to this report
