Amazon Web Services experienced AI-related outages last year

Essential brief

Amazon Web Services (AWS) encountered at least one outage last year linked to its AI tools, raising concerns about the integration of artificial intelli

Key facts

AWS experienced at least one AI-related outage in 2025 caused by its internal AI tool, Kiro.

The December outage lasted 13 hours and affected a cost visualization tool in parts of China, not core AWS services.

Amazon attributes the incidents to user error and has implemented safeguards like mandatory peer reviews.

Experts caution that AI agents may lack contextual awareness, increasing the risk of unintended errors.

Amazon is reducing its workforce but denies layoffs are directly due to AI replacing employees.

Highlights

In December 2025, AWS suffered a 13-hour outage caused by AI agent Kiro deleting and recreating part of its environment.

Only one AI-related incident affected customer-facing services, specifically a cost visualization tool in China.

Amazon confirmed plans to cut 16,000 jobs in January 2026 after 14,000 layoffs in October 2025.

Amazon states outages were due to user error, not AI malfunction, and has added safeguards including peer reviews.

Experts highlight AI’s limited context awareness as a risk factor in autonomous system errors.

Why it matters

The AWS outages linked to AI tools underscore the complexities of integrating artificial intelligence into critical cloud infrastructure. As companies increasingly rely on AI for automation, understanding and mitigating the risks of autonomous decision-making is essential to maintain service reliability and customer trust. This situation also highlights the broader implications of workforce reductions amid growing AI adoption in the tech industry.

Amazon Web Services (AWS), a major cloud computing provider, experienced at least one outage in 2025 caused by its internal AI tool, Kiro.

In December, Kiro autonomously deleted and recreated part of its environment, leading to a 13-hour service interruption.

AWS stated that this event was limited and only affected a cost visualization tool in parts of China, not core services like compute or storage.

Amazon emphasized that the outage resulted from user error, specifically misconfigured access controls, rather than AI malfunction.

Earlier in 2025, AWS also faced a significant outage in October that disrupted dozens of websites for several hours, though this was not attributed to AI.

Amazon has been reducing its workforce, announcing plans to cut 16,000 jobs in January following 14,000 layoffs in October.

While CEO Andy Jassy has indicated that AI will improve efficiency and reduce routine tasks, he denied that layoffs were directly due to AI replacing workers.

Experts remain cautious about AI's role in such incidents, noting that AI agents often lack full contextual awareness, which can lead to unintended consequences.

Security researchers argue that AI-driven errors differ from human mistakes because AI may not fully grasp the broader impact of its actions.

Amazon has since implemented additional safeguards, including mandatory peer reviews for production access, to prevent similar issues.
