Before now, I haven't seen any verifiable statements about how the networking infrastructure in the Pentagon was affected by the attacks last year. Not to diminish the loss of life, which was tragic, but networking people might be interested in this. Building a surviable network in such a small area, relatively speaking the Pentagon is small, is a much harder problem than diversity on a regional or even national network. http://www.fcw.com/fcw/articles/2002/0812/news-dod-08-12-02.asp "Among the problems DOD encountered Sept. 11 was a computing environment with many points of failure -- applications or databases that, if removed, could not be recovered and critical network links that, if down, could not be worked around. DOD officials have said that the terrorist attacks were a dramatic wake-up call. The attacks severed one of the Pentagon's main communications lines and destroyed some Army and Navy servers."
