No, I understand networking hardware quite well actually. I'm also familiar with Room 641A. Room 641A did not capture 80% of internet traffic. If you think 80% of internet traffic could be routed through Room 641A you're not thinking about the infrastructure required to get it all there. It was a targeted operation on backbone lines that were right there.
