Amazon’s cloud division reportedly suffered outages last year after an internal AI agent altered system settings.
One disruption in December lasted about 13 hours when the tool deleted and recreated part of its environment.
The company said the incidents were limited and blamed misconfigured access controls rather than artificial intelligence.
It added that only one event affected customer-facing services.
The reports have raised questions about Amazon’s rapid AI expansion as it cuts thousands of jobs.
Andy Jassy has said automation will reduce routine work and shrink the workforce over time.
Some cybersecurity specialists dispute Amazon’s explanation.
They argue AI systems can act quickly without fully understanding wider consequences.
This can increase the risk of large-scale errors if safeguards are weak.
AWS powers major websites and public-sector systems, including many UK government services.
Past outages have already highlighted the risks of relying on a small number of cloud providers.
Amazon says it has introduced extra controls, including mandatory peer review for production access, to prevent similar incidents.
