It is remarkable when organization change from risk avoidance to risk preparedness. Many companies build systems (computer or otherwise) and hope the big issue never happens. Eventually, it does.

I was called out as crazy the first time I walked into our data center to perform “pull the plug” testing in the middle of the day. We found issues and needed a MS patch to be 100% ready to go. We had a few minutes of downtime during the test, but it would have been much longer had it occurred in the middle of the night with nobody ready to work the issue.
