Chambers apologized AT&T for FR NW outage AT&T blames switching equipment for outage Mercury News Staff and Wire Reports AT&T Corp. on Tuesday blamed problems with two pieces of switching equipment -- made by San Jose-based Cisco Systems Inc. -- for the computer network problem that crippled automated teller machines and credit card systems nationwide for almost a day. Yet even after service was restored Tuesday afternoon, officials at both companies said they weren't sure what the root cause of the outage was. AT&T is the nation's largest supplier of data network services to companies. The collapse of the company's ''frame-relay'' network affected only a portion of its customers -- and had no impact on conventional or cellular phone service. Still, it was the worst such failure ever, industry experts agreed. ''This sort of thing is going to happen infrequently, but more and more in the future,'' said Howard Anderson, managing director of the Yankee Group, a technology research firm. ''And it makes you realize how vital to the lifeblood of the economy these complex computer networks have become.'' Anderson had firsthand experience with the problem. He said he had just emerged from a Tower Records store in San Jose where there had been a long line of frustrated customers whose credit card transactions could not be processed. ''I had cash, so it was great for me,'' Anderson said. ''I went straight to the front of the line.'' Throughout California, probably a thousand of AT&T's business customers were affected, a company spokeswoman estimated. Among them was Wells Fargo, which connected about half of its branches and automatic teller machines to the company's central computers in Sacramento through AT&T's frame-relay network. The branches stayed open after the outage but the bank machines shut down, prompting Wells Fargo to scramble for another way to connect the automatic tellers to the company's computers, said spokesman Mark Marymee. Working with MCI Communications Corp. and 3Com Corp. and the Roseville Telephone Company, a local phone company near Sacramento, Wells Fargo had almost all of its connections re-established by the time branches opened Tuesday, Marymee said.
