The Radar on Internet Threat page has proved extremely popular, especially during periods of heightened tension where we experience hit rates of 12K/hour.

25 Jan 2006 President Bush can be seen standing in front of our radar page during his visit to the National Security Agency (NSA) at Fort Meade, the NSA is just one of our high profile visitors, though it is very rare that we see inside their operations centres. The footage of this visit was seen on CNN, NBC and featured by a host of newspapers, from the US to China.  Many thanks to our supporters  for making us aware of our unexpected photo call.
