In a Government Computer News article there was an interesting fact mentioned which hints at Army's cyber command centers ability to handle contigency issues.
It was stated that many of their links utilize undersea cables but some also use land based fiber. One of such land links was severed by a garbage truck, disabling service to their northern and southern continental CC for several hours.
Now, I know how difficult it can be to design and run a full contigency operation but one would think that with the budget and resources of a government such a goal should not pose too much of a problem. Apparently, this is not so for Army's cyber ops.
To be honest, it's a big surprise to me. I've seen companies not lose a single tcp connection upon core router/switch failures, cable cuts in server racks, and power outages in data centers and they don't have the same resources as the government can afford.
This isn't a good sign especially in light of more and more talk regarding large scale cyber warefare. Hopefuly, that garbage truck incident served as a lesson. On a bright side, at least the guys at the monitoring consoles got a decent break :)
