"Arrowhead Global Solutions, Inc. has announced the successful roll out of the US Critical infrastructure Warning Information Network (CWIN) to all 50 states and the District of Columbia. The implementation of CWIN's network connectivity to the states by the Department of Homeland Security provides a survivable line of communications for use particularly when the public networks are unavailable. Operational since 2003, CWIN is the survivable link in the Homeland Security Information Network (HSIN), connecting DHS with the vital sectors that restore the Nation's infrastructure during emergencies; the states' homeland security advisors; and appropriate federal agencies. CWIN has no logical dependency on the Internet or the public switched network, and remains viable under emergency conditions to provide key decision-makers with the ability to direct and manage incident response activities".
