"In 2003," reports The Washington Post, "Room 641A of a large telecommunications building in downtown San Francisco was filled with powerful data-mining equipment for a 'special job' by the National Security Agency," where copies of e-mails and other online traffic was siphoned from one of the largest Internet hubs in the United States. As the report explains, "What occurred in the room is now at the center of a pivotal legal battle in a federal appeals court over the Bush administration's controversial spying program, including the monitoring that came to be publicly known as the Terrorist Surveillance Program."
