I spent 4 decades working throughout the system administrator world and found myself in some truly silly building locations on a few continents (wildfire, flood plain, earthquake, volcano, tsunami, aside rail lines, under flight paths, etc.) and other such places chosen for (?) reasons. Apart from the trains and planes, the natural risks did not seem to be taken seriously. Is there a superior location anywhere for building an IT fortress (not an office space) against natural disaster, to the best extent possible. Suggestions?
