Recent AWS outages blamed on AI tools - at least two incidents took down Amazon services

• At least two recent Amazon outages were caused by misconfigured AI tools
• Amazon asserts incidents were "user error, not AI error"
• The company has implemented "numerous safeguards"

At least two recent AWS outages were caused by incidents involving Amazon's own AI coding tools, the company has said.

A report by the Financial Times (FT) notes a 13-hour interruption in mid-December 2025 was the result of Amazon's Kiro AI coding agent, which had reportedly decided to delete and recreate the environment.

Although AWS had published an internal report on the cause of the issue, this was never shared publicly, but the FT has obtained the information from four unnamed people familiar with the matter.
