OAKLAND, Calif. (AP) - A San Francisco Bay Area transit agency is blaming a network server upgrade for a computer problem that shut down train service.
Bay Area Rapid Transit agency spokeswoman Alicia Trost says BART implemented the planned upgrade on Thursday, but it later began affecting the performance of the computer system used to monitor train service. The system eventually went offline.
Service was delayed on Thursday night and only started back up around 7:15 a.m. Friday, a little more than three hours later than normal.
Trost says the server has been returned to its original configuration now and the problem fixed.
The disruption came as BART's board approved a tentative labor deal that ended a strike, but stripped out a provision supported by unions.
The move has created uncertainty about the fate of the deal.
