People will down vote you, but when I worked for a mega corp and a hurricane knocked out our office, they had a plan, and it worked: they set up in a hotel, and continued operations, people stayed employed, people got the products (which were largely essentials) in their supermarkets, etc.

This is not like, super trivial. People needed to figure out power, hardware, networking, vpn, etc.. etc.. etc.. and staffing. A lot of that had absolutely nothing to do with IT, but some of it did.
