Amazon's retail website experienced a series of outages, including a significant six-hour disruption, with at least one incident attributed to an engineer following inaccurate advice from an AI tool. Internal documents revealed that "GenAI-assisted changes" were a factor in a "trend of incidents" stretching back to the third quarter of 2025. The most severe incident on March 5 caused a 99% drop in orders across Amazon's North American marketplaces, leading to an estimated 6.3 million lost orders. Another incident on March 2 resulted in nearly 120,000 lost orders and 1.6 million website errors due to incorrect delivery times. Dave Treadwell, Amazon's Senior Vice President of eCommerce Foundation, convened a "deep dive" meeting to address the "string of Sev 1s." The company clarified that only one incident involved AI tools, and none involved AI-written code, but rather an AI tool inferring bad advice from an outdated internal wiki. Amazon implemented a 90-day temporary safety guideline and required additional review for "GenAI-assisted" production changes. AMZN shares traded at $207.67, down 0.89% on the day.
