This is a good reminder that no system is immune to failure, cloud or otherwise. Georedundancy is expensive and difficult, so it's a delicate trade-off, but engineering good physical backup systems is also difficult.
Our servers are in a state far away from hurricanes, but in a state with many other natural disasters, including tornadoes, so it's hard to say if it's a good trade or not. Interesting question: why aren't there more DCs in Utah, Wyoming, Idaho, or New Mexico? And is physical location a huge determinant in where you colo your servers?
