Loudoun County is the wealthiest county in the United States by median household income and hosts Data Center Alley in Ashburn — where approximately 70% of global internet traffic passes through data centers operated by AWS Microsoft Google Meta and dozens of others. Washington Dulles International Airport creates aviation emergency planning requirements. The Potomac and Goose Creek watersheds create flooding risk. A major power grid failure or cyberattack targeting Loudoun County's data centers could disrupt global internet communications.
