In 2009 I had a pair of (what I thought at the time) very cleverly architected VM servers with complete redundancy between them. Either one could be pulled and there'd maybe be a few seconds of data loss at the worst. One day lightning struck the building and even managed to "jump" the grounded pair of UPS's and fried all hard disks in both nodes.

Thankfully I had both onsite and offsite backups; but it took a couple of weeks to order the new equipment, install it and set everything up again.

Now I "devops" all the things and always have the ability to spin up all the services and restore from backups within minutes. This is the new standard in my opinion.
