In the middle of a disaster is the worst possible time to discover that the backups won’t load, the cloud service provider can’t be reached, the firewall has a leak, and the one guy
with all the key passwords is at a no-phones-allowed yoga retreat.
In a disaster, people panic. Lines of communication break down. People forget what they’re supposed to do, make mistakes because they’re in a rush, or just hide and hope that the problem
goes away. Disaster preparedness plans go out of date quickly as people move around and as infrastructure is reconfigured.
