SAN FRANCISCO — Bay Area Rapid Transit engineers are conducting “a comprehensive forensic evaluation” to determine what caused a shutdown of the BART system on Saturday.
The Saturday morning outage began about 6 a.m.; service was not fully restored until about 11 a.m., the San Francisco Chronicle reports. BART’s preliminary report is that the closure was because of a computer network failure affecting the power and routing systems. It was the first such significant system outage in 15 years, a member of the BART board told the Chronicle.
BART’s statement on the outage said the evaluation “is expected to take several days due to the complexities of our system.”
