Overview

• BART halted the start of service Friday across the entire system due to a computer equipment problem linked to overnight network work, then restored full service shortly before noon.
• Engineers identified equipment at San Francisco’s Market Street location as the likely failure point, and the agency says a forensic review is underway.
• A BART board member acknowledged that a redundant backup network pledged after a 2019 failure was not in place when Friday’s outage occurred.
• The shutdown stranded thousands and pushed riders to AC Transit buses, San Francisco Bay Ferry trips and congested roads, with Muni reporting related delays.
• Following the disruption, Bay Area lawmakers said the state Department of Finance has not finalized a $750 million loan before next week’s deadline, warning of severe service cuts such as hourly trains and station closures if the bridge funding falls through.
