Amazon tightens AI code guardrails after outages
After GenAI-related outages, Amazon now requires senior engineer sign-off for AI-generated code changes by junior and mid-level engineers reported.
The internal briefing identified a "trend of incidents" with a "high blast radius" linked to "Gen-AI assisted changes". This followed a six-hour outage on March 5 that impacted Amazon's website and app, causing issues with checkout, login, and pricing. The new policy requires senior engineer sign-off for AI-generated code changes made by junior and mid-level engineers. This is meant to address "novel GenAI usage for which best practices and safeguards are not yet fully established". Amazon insists that AI coding isn't the primary source of the outages. They attribute the incidents to user error, specifically misconfigured access controls, not inherent flaws in the AI tools themselves. The company is implementing "temporary safety practices which will introduce controlled friction to changes in the most important parts of the Retail experience". This includes combining AI-driven tools with rules-based systems to ensure accuracy. Amazon is also requiring engineers to document code changes more thoroughly and secure additional approvals.
