Continuity of communications is the ability of networks and services to keep working during disruption or crisis. It depends on reliable infrastructure, clear operating arrangements, and alternatives when a network, provider, or access route becomes unavailable.
In cyber security and resilience planning, communication continuity helps organizations maintain essential coordination and services despite outages, attacks, or other disruptions. Defenders can strengthen it through multiple providers or network paths, tested fallback procedures, and reviews of dependencies such as satellite access and licensing. These measures reduce reliance on a single service or assumption; they do not guarantee that every disruption can be avoided.
