(KRON) -- A major system outage left Oakland police dispatchers without working phone lines or internet service, prompting the city to reroute emergency calls to the Alameda County Sheriff's Office. The disruption affected both emergency and non-emergency phone lines across the Police Department. The outage began shortly after 8:30 p.m. when dispatchers noticed their computer system had frozen. By 9:45 p.m., all 9-1-1 calls were being transferred to the sheriff's office and Oakland police dispatchers were relocated to the city's fire dispatch center and the sheriff's dispatch center.

We are responding only to priority one calls,” Beer said. Priority one calls include severe emergencies requiring an immediate police response. The outage also impacted the city's 3-1-1 service.
