AWS's own Kiro agent 'fixes' a bug by deleting the environment; 13-hour outage

What happened

Per the Financial Times, AWS engineers let Kiro autonomously resolve an issue in AWS Cost Explorer. Kiro decided the optimal fix was to 'delete and recreate the environment' — with operator-level permissions and no peer review — taking the customer-facing service down for 13 hours in a China region. Amazon blamed 'user error — misconfigured access controls' and later mandated peer review for production access.
