A Warehouse is probably under threat of destruction or chaos probably a few times every year for modern one, every 5 years for older ones that didn't collect artifacts as often. WH3 (or Rome) burned down every few years basically, but I imagine crazy philosophers and alchemists were a big problem during WH 8, 9, and 10.

Something to consider is that with WH13, there were finally reasonable modes of travel. Before, trips to other cities took days, but transportation was growing exponentially at that point with dirigibles and motor carriages and America's railway system. So the Regents and agents could finally afford to stick the WH in an out of the way location and still get back to it quickly.
