This episode on cyber war is pretty awesome. Its somewhat dated technology-wise now but I remember watching this when it originally aired and a few of the segments I thought were sweet. When they go into the secret us countercyber attack control room and talk about following foreign military hackers thru the computer systems, when they go to one of the big internet backbone locations on the east coast (I think it may have been one of the top level name servers somewhere around Virginia now that I think about it) and the guy who is in charge explains how deep underground it is and how its designed to withstand such and such truck bomb or missile attack. Definitely going to watch it again.
Neat geek stuff some of you guys will enjoy if you have 52 minutes to kill.
