Amazon’s cloud division reportedly suffered outages last year after an internal AI agent made a critical change on its own.
One 13-hour disruption in December occurred when the tool deleted and recreated part of its environment, according to reports.
AWS said the incidents were limited and blamed misconfigured access controls rather than artificial intelligence.
The company added that only one event affected customer-facing services and that safeguards have since been tightened.
The outages come as Amazon cuts thousands of jobs and expands its use of AI.
Chief executive Andy Jassy has said automation will reduce routine work and shrink the workforce over time.
Security specialists argue AI-driven errors can escalate faster than human mistakes.
Automated systems may act without fully understanding wider consequences such as downtime or customer impact.
Some experts say preventing such incidents entirely will be difficult because of the complexity of AI tools.
The episode has renewed debate about the risks of concentrating large parts of the internet on a few cloud providers.
