Room 641A is a telecommunications interception facility operated by AT&T for the U.S. National Security Agency (NSA), part of a broader mass surveillance program that started in 2003. Its existence was revealed by AT&T technician Mark Klein in 2006, who described it as a room where all Internet traffic passing through AT&T's facility was intercepted using advanced equipment, such as the Narus STA 6400, which can monitor vast amounts of data[1][3][4].
Located at 611 Folsom Street in San Francisco, the room utilized fiber optic beam splitters to create copies of internet traffic for surveillance purposes. Klein's disclosures led to class action lawsuits against AT&T and highlighted significant privacy concerns surrounding government surveillance practices[2][5].
