Incident Analysis: 13-Hour AWS Cost Explorer Outage in Mainland China Linked to Kiro AI Tool

December 15, 2025

On a winter day in mid-December 2025, Amazon Web Services (AWS) reported a nearly 13-hour interruption of the Cost Explorer service in one mainland China region. The outage was allegedly due to an internal AI coding tool, Kiro, making changes and deleting/recreating parts of the environment. However, Amazon contested this claim, asserting that the incident was a rare occurrence caused by user error and misconfigured access controls, not AI-related.
