California City Declares Emergency After Cyberattack Disrupts 911 and Public-Safety Systems

A California city has declared a state of emergency after a cyberattack disrupted systems supporting 911 calls, police and fire dispatch and other municipal operations. Suisun City officials said malicious software compromised the city's information-technology environment, prompting officials to shut down the network to contain the intrusion and preserve evidence. The incident affected 911 routing, police and fire dispatch, municipal records and other city services. Emergency calls were redirected through the Solano County dispatch center while public-safety personnel continued responding to incidents. The city is working with federal and state agencies while systems are investigated and restored. Officials have not publicly identified the attacker, the malware involved or the intrusion method, and there has been no confirmed disclosure of stolen data. The incident highlights how municipal cybersecurity failures can become public-safety continuity problems rather than solely IT outages.
