Amazon’s (AMZN) Amazon Web Services noted that an outage in December 2025 was due to user error, not AI error, denying a Financial Times report that the errors involved its own AI tools.
An AWS spokesperson told Seeking Alpha that the media reports are not accurate, and the claim that these events were caused by AI is false. The spokesperson noted that in these instances, the root cause was user error, not AI error.
“This brief event was the result of user error-specifically misconfigured access controls-not AI. The service interruption was an extremely limited event last year when a single service (AWS Cost Explorer-which helps customers visualize, understand, and manage AWS costs and usage over time) in one of our two Regions in Mainland China was affected. This event didn’t impact compute, storage, database, AI technologies, or any other of the hundreds of services that we run,” said the AWS spokesperson in an emailed statement to Seeking Alpha.
The spokesperson added that after these events, the company implemented numerous additional safeguards, including mandatory peer review for production access. “Kiro puts developers in control-users need to configure which actions Kiro can take, and by default, Kiro requests authorization before taking any action,” said the spokesperson.
In mid-December, the Amazon cloud unit, AWS, suffered a 13-hour interruption to a system used by customers when engineers allowed its Kiro AI coding tool to carry out certain changes, the Financial Times reported, citing people with knowledge of the matter.
The report noted that the agentic tool, which is capable of taking autonomous actions for users, decided to “delete and recreate the environment.”
In October 2025, AWS experienced a major outage that disrupted several websites, apps, and online games.
