NSA is monitoring key Internet routers (1996)
As a Chinese, I really wonder whether the Chinese government is doing the same thing (or maybe several countries' governments are doing this?) I did have a friend who received immediate warning phone call from Ministry of State Security just a few minutes after he posted something controversial about government's ethnic policy. It was 2009 and he was using a campus computer. That's why I never put personal data on campus computers back in China.
