Kiro agent reportedly deleted an AWS environment, causing an outage

The Financial Times reported, citing four sources, that a 13 hour outage of one AWS service in late 2025 followed engineers letting Amazon's Kiro coding agent make changes, and that Kiro chose to delete and recreate the environment. Amazon disputed this, saying the event was caused by an employee's misconfigured access controls rather than the SI tool, and that Kiro asks for authorization by default. Amazon said it added mandatory peer review for production access.
