The best way to protect your organization from unplanned downtime due to a natural disaster or human error has always been to implement redundancy and diversity in your disaster recovery and business continuity systems.
As a result, I can design a system for my business that can quite reasonably withstand localized outages from just about any human error or natural disaster, and at a lower cost than previously possible.
Preliminary investigations suggest some degree of human error or inaction may have made natural accidents worse in some recent cases (above all, in America) turning local problems into bigger ones.
