// Strategic Significance
The Herndon area transmission substations in Northern Virginia are critical to powering the Ashburn data center corridor which carries 70 percent of global internet traffic. Any major substation failure in Northern Virginia would simultaneously black out the worlds most important internet infrastructure. The concentration of critical internet infrastructure dependent on this relatively small geographic power grid creates extraordinary systemic risk.
// Civilian Impact Assessment
Fairfax County with 1.1 million residents and the Northern Virginia data center corridor serving global internet infrastructure. A major substation failure would black out AWS US-EAST-1 and the Ashburn data centers affecting internet service for hundreds of millions globally. The federal government corridor in Northern Virginia depends on this power infrastructure.
