Officials in Suisun City, California, declared a local state of emergency after a cyberattack breached municipal information technology systems and disrupted critical public services, including parts of the city’s 911 emergency call system. According to a report by the New York Post, malicious software infiltrated the city’s IT infrastructure at approximately 5:45 am on August 7. To prevent the attack from spreading and to preserve digital evidence, administrators disconnected the entire computer network. Authorities have not disclosed the specific software used or identified suspects.
Emergency Services Rerouted as Network Disconnected
Despite the operational disruption, city officials confirmed there is no immediate threat to public safety. Police, firefighters, and emergency responders continue to operate, with incoming 911 calls being rerouted through the Solano County dispatch center to maintain continuous service. However, the breach impacted city records, online services, and internal systems, rendering several municipal functions temporarily unavailable. In response, the Suisun City Council unanimously approved a local state of emergency during a special meeting on Saturday.
Federal and State Agencies Join Forensic Investigation
The emergency declaration allows the municipality to access additional emergency resources and seek reimbursement for costs incurred from the attack. City officials are collaborating with the Federal Bureau of Investigation, the US Department of Homeland Security, the California Office of Emergency Services, and other state and regional agencies to investigate the breach. Authorities have also activated the Emergency Operations Center as investigators work to determine how the attackers gained network access and who was responsible.
Containment Measures and Restoration Efforts Continue
City leadership emphasized that shutting down the entire computer network was a necessary step to contain the cyberattack and preserve crucial evidence for the ongoing investigation. Located about 45 miles from both San Francisco and Sacramento, the Solano County municipality is working to safely restore affected systems while ensuring essential emergency services remain available to residents throughout the recovery process.
