San Francisco’s BART subway system is back up and running after service was suspended and shut down on Friday morning due to a “computer networking problem.” The service is back online “system wide” as of about 9:17AM PT, but BART says to “expect major delays in service toward all destinations due to an earlier train control problem.”

The system had initially been suspended “until further notice” around 5AM PT and BART had alerted riders to “seek alternative means of transportation.” As of 9AM PT, BART had suspended service in San Francisco and San Mateo County stations and had enabled limited service again in East Bay. Here is the last service advisory alert before service came back online:

BART is offering limited East Bay service at this time due to a train control problem. Blue Line trains will run between Dublin/Pleasanton and MacArthur stations. Yellow Line trains will run between Antioch and MacArthur stations. Orange Line trains will be normal running. There is no Red or Green Line service at this time.
