There was an old joke: "To err is human, but to really foul up you need a computer." Now it seems the reverse is true. The reliability of data center equipment is vastly improved but the humans running them have not kept up and it's a threat to uptime.
The Uptime Institute has surveyed thousands of IT professionals throughout the year on outages and said the vast majority of data center failures are caused by human error, from 70 percent to 75 percent.
And some of them are severe. It found more than 30 percent of IT service and data center operators experienced downtime that they called a “severe degradation of service” over the last year, with 10 percent of the 2019 respondents reporting that their most recent incident cost more than $1 million.
