To me, the more important part would've been the solutions they'll come up with to avoid something like this happening again. Is it going to just be "add a line to the playbook asking the engineer to double check the command" or will they make big changes across the system to prevent things like this happening.
I'm interested in something like that, too! I've got a few destructive Ansible commands that I check a few dozen times before running. But There's always a chance that I'm tired/distracted/whatever and run something silly anyway. Typically I put in things like config test checks and prompts, but damn it's scary how much power I have with this Ansible setup. I definitely don't want to be in this AWS position.
