A "hot site" is a fundamental concept in business continuity and disaster recovery planning. It refers to an alternate facility that is fully equipped with the necessary computer hardware, software, telecommunications infrastructure, and environmental controls. It is designed to be a mirrored or near-mirrored replica of the primary production site, allowing an organization to resume critical operations within a very short period (typically hours) following a disaster or major disruption at the primary location.

A. This describes a radiological or hazardous material (HAZMAT) contamination zone, which is unrelated to the business continuity definition of a hot site.

B. This is a law enforcement or criminal justice term for a place where stolen goods are kept, which has no connection to disaster recovery.

C. This describes a specific type of equipment failure or environmental issue within a facility, not a pre-planned, fully functional alternate recovery site.
