Even the best websites with the most carefully laid continency plans don’t always achieve 100 percent uptime. There is, however, a vast difference between properly mitigated website downtime and instances of downtime that leave the world wondering how things could have gone so horribly wrong. For example, if a website goes down for a day due to a power outage, we wonder where the backup servers are and why they haven’t been implemented. Then we find out there were never any backup servers in place to begin with. That is a facepalm moment.
