This is exactly right. The truth is you can spend infinite money on various scenarios, and that cost has to be paid. The manufacturer side of this is 'warranty', you guarantee that something won't break in 90 days, a year, 5 years, what have you and you price to that probability.

Another risk in New York that will take data centers offline, earthquake. It will happen at some point, but the chance of it happening in the next 100 years small (contrasted to Santa Clara where we're much more likely to get an earthquake than a flood). So you could pay to have your Manhattan high rise put onto base isolators and proofed against an earthquake, but what size earthquake? Magnitude 3? Magnitude 6? Magnitude 9? And then if your building is still standing brightly after the Magnitude 9 earthquake are your fiber optics still there? How about the network tie point? Did it fall into a hole in the ground? So the cost to make all of Manhattan resistant to a 9.0 earthquake?

Its impressive that they are carrying up the fuel. I might be inclined to see if I could tractor in a 12kW generator to run one elevator. Sure you'd be burning fuel at both ends but it would be easier on the crew hauling the petrol.
