The city's IT systems were breached on Friday, prompting officials to shut down the entire network to contain the threat and preserve evidence for an ongoing federal investigation.
Officials stated that residents are not in immediate danger, as emergency crews remain operational. Dispatch calls are being routed through the Solano County dispatch center, and police and fire personnel continue to respond to service calls. The cyberattack also impacted city records and other municipal services, rendering online services and internal operations temporarily unavailable.

Federal and state agencies, including the FBI, the Department of Homeland Security, and the California Office of Emergency Services, are collaborating with city officials. The city has activated its Emergency Operations Center as investigators work to determine the entry point of the malicious software and identify the perpetrators. As of the declaration, information regarding the method of the breach or suspects has not been released.
