System(s), method(s), and device(s) that enable recovery of a core network (e.g., UMTS, GSM) during a disaster or other disruption are presented. A service recovery controller component can monitor connectivity in the communication network, can detect a disruption or loss of connectivity in the packet-switched (PS) core network, and, when a disruption or loss of connectivity is detected, can automatically re-route data or voice traffic between a radio network controller(s) and an internet protocol (IP) multimedia subsystem (IMS) core network via a direct interface(s) to enable communications to continue between communication devices. The service recovery controller component can continue to monitor connectivity in the communication network, and can detect when connectivity is re-established with the PS core network. When connectivity is re-established, the service recovery controller component can route data or voice traffic via the PS core network.
