Comment Grid Fails, it happens (Score 1) 359
Ice storms can often make tree branches break onto powerlines and in extreme cases have put enough ice on the power lines themselves to make them sag to the ground and bend telephone poles.
Missouri and Oklahoma, a couple of years ago had one of the worst ice storms in 20 years. Followed by a few days of serious work to repair them and almost a year worth of clean up from all of the destruction that the ice made. Looking at the scene after the event it looked like a hurricane had hit.
I doubt America is in big trouble. There is no way to mount a serious DDOS attack without removing anonymity and making yourself a target by physically connecting to the grid. Americans can deal with a few days of power failure. Nature itself has already put us in a position to be ready for grid failure.
