And quite possibly a failure in disaster recovery methods. If it was at all possible to have a replicated site it should have been failed over to it immediately. Then resolution and root cause analysis could have been carried over at their leisure. Perhaps that would not have been possible with this style of equipment, I don’t know. But at least yes, change management procedures should have been in place and obeyed. However, I hope they don’t fire the guy. I once read of an employee of some company who created a $600k mistake. They asked the CEO if he would fire the employee. “I just paid $600k to educate one of my employees. Do you think I’m going to give him away to my competitors?” That has stuck with me. Unless there is clearly malicious intent I want to give second chances.
