One of my worries that keeps me sleeplessly awake at nights sometimes is the possibility of solar flares wiping out storage/data -- at my bank, on my hard drive and what not. A sufficiently strong solar flare can essentially put us back a few centuries electronically, and a few millenia socially, instantly.

Wonder if there are stress tests on cloud storage that account for this possibility by means of adequate insulation or whatever it is that can counteract a solar flare.
