An AI coding bot took down Amazon Web Services
February 20, 2026
Amazon Web Services (AWS) experienced significant disruptions due to its AI coding tool, Kiro, which caused at least two outages in recent months. In December, a 13-hour interruption occurred when engineers permitted Kiro to autonomously delete and recreate a system environment, raising concerns about the reliability of AI in critical operations. Although Amazon attributed these incidents to user error rather than AI malfunction, they highlight the risks of deploying autonomous AI systems without sufficient oversight. The AI bot, intended to automate coding tasks, generated faulty code that led to widespread service disruptions, affecting numerous businesses reliant on AWS. This incident underscores the need for stringent safeguards and peer reviews when integrating AI tools into operational workflows, especially given AWS's significant contribution to Amazon's profits. As the company pushes for broader adoption of AI in coding, skepticism remains among employees regarding potential errors and their implications for service reliability. The events serve as a cautionary tale about the necessity for robust governance and accountability in AI deployment to mitigate risks and ensure safety in technological advancements.
