SUISUN CITY, CA — The Suisun City Council declared a state of emergency Saturday after a cyberattack that shut down computer systems including 911 public safety operations.
"Malicious software infected and compromised" the East Bay community's information technology systems beginning about 5:45 a.m. Friday, the city said on social media.
"The cybersecurity incident hit critical public safety operations, including 911 routing, police and fire dispatch, records and city services," the city said.
"There is no imminent threat to the public," the city said. "All public safety services remain active."
The city shut down its computer network "to contain the threat and preserve evidence for a federal investigation," it said.
The city, with a population of about 30,000, said it is working with the FBI, Department of Homeland Security and California Office of Emergency Services to investigate the incident and restore systems.
The state of emergency, approved at a special meeting of the council Saturday morning, allows the city to access emergency support services and to recoup costs of the cybersecurity incident, it said.
Suisun City dispatchers were taking calls for service through the Solano County dispatch center. Suisun City police officers and firefighters continued responding to calls for service, the city said, but online city services and internal operations were unavailable.
