Amazon Web Services suffered a 13-hour outage to one system in December as a result of its AI coding assistant Kiro’s actions, according to the Financial Times.
Numerous unnamed Amazon employees told the FT that AI agent Kiro was responsible for the December incident affecting an AWS service in parts of mainland China.
It is not the only time AI coding tools have caused problems for Amazon.
A senior AWS employee said the December outage is the second production outage linked to an AI tool in the last few months, with another linked to Amazon’s AI chatbot Q Developer.
