There was a big T-splitter in NYC back in the 90s that would route copies of eastern seaboard and transatlantic telecom (voice) traffic. I don't know which TLA was attached. And then there was the DNS/Internet stuff in Crystal city about the same time. There was all the KDC back-door administrivia out of Maryland too, but that was less interception of traffic and more making sure they had the keys to decrypt it all...
