Bay Area Rapid Transit (BART) service has been fully restored Friday, after the agency dealt with a computer outage that shut down the entire system during the morning commute.

BART says that service has been restored systemwide following an hours-long outage during the morning commute. The transit agency says to expect major delays to all destinations.

BART carries nearly 175,000 people most weekdays. The system went down shortly after 5 a.m. and service wasn't fully restored until around 9 a.m., complicating morning commutes. BART also runs to the San Francisco International Airport. Alternate ferry and bus service stepped up to help passengers reach destinations.
