Cause of Outages
Earlier this year, I was researching some of the largest IT outages of 2021. They all, the ones which stated the cause, were due to a configuration change.
Think about that for a moment.
Large companies with everything redundant were brought down by a configuration change.
This tells me 2 things:
1). Those organizations need to invest in a better Service Management organization, especially CMDB. They had no idea of the change risk or relationship between CIs.
2). Billions of dollars were spent on redundancy and hardening the infrastructure without a true view of risk. In the same way, many organizations have experienced security breaches from third-party partners.
