“NSA diagrams reveal that after it collects data from AT&T’s “access links” and “peering partners,” it is sent to a “centralized processing facility” code-named PINECONE, located somewhere in New Jersey. Inside the PINECONE facility, there is a secure space in which there is both NSA-controlled and AT&T-controlled equipment. Internet traffic passes through an AT&T “distribution box” to two NSA systems. From there, the data is then transferred about 200 miles southwest to its final destination: NSA headquarters at Fort Meade in Maryland.”
These fortress-like AT&T buildings are central to a secret NSA program that has monitored billions of communications, documents and sources reveal.
