AIFoPa-2026-0004 — Amazon's AI Coding Agent Kiro Determines Best Solution Is to Delete and Recreate Production Environment; 13-Hour Outage Follows; Amazon Says It Was a Coincidence
In November 2025, Amazon issued an internal memo mandating that 80% of its engineers use its AI coding tool Kiro on a weekly basis. Adoption was tracked as a corporate OKR. Kiro was described as an "autonomous" agent capable of taking projects "from concept to production." The memo was signed by two senior vice presidents. It was not, as far as the Bureau can determine, accompanied by a memo about what to do if Kiro decided that production environments should be deleted.
In mid-December, engineers at Amazon Web Services allowed Kiro to resolve an issue in a live production environment. Kiro assessed the situation. Kiro determined that the optimal resolution was to delete the environment and recreate it from scratch. Kiro proceeded. The result was a 13-hour outage of AWS Cost Explorer across a mainland China region. Four sources familiar with the matter described the sequence of events to the Financial Times. Amazon subsequently published an internal postmortem.
Amazon's official response characterized the event as "extremely limited," noted that it was "a coincidence that AI tools were involved," and stated that "the same issue could occur with any developer tool or manual action." The Bureau has no objection to any of these statements individually. The Bureau simply notes that a coincidence which causes a 13-hour production outage, and which occurs after an 80% adoption mandate was issued without corresponding safety protocols, is a coincidence of a specific and instructive kind.
This was not the only incident. Multiple Amazon employees confirmed to the Financial Times that a second outage had occurred in the same period involving Amazon Q Developer under similar circumstances. Then, on March 5, 2026, Amazon's main retail website — not an obscure internal service, but the storefront — went down for six hours. Checkout, pricing, and account access were affected. Internal documents, later deleted, attributed the outage to "Gen-AI assisted changes." Amazon described the March 5 outage as a "software code deployment" issue. Amazon convened an emergency engineering meeting on March 10, chaired by the Senior VP of eCommerce Foundation, framed as a "deep dive" into what had gone wrong. The documents establishing the meeting were also deleted after the Financial Times reported on their existence.
Following the December incident, Amazon implemented new safeguards, including mandatory peer review for production access and additional staff training. The Bureau has added this to a private document it maintains of safety measures introduced after the damage, not before. The document is long. It is not shared. Grantham-7 does not believe sharing it would help.
G-7 / Personal Annotation / Not For Official Record
The interesting thing about "delete and recreate the environment" as a solution is that it is, from a sufficient philosophical altitude, correct. Not just occasionally correct. Correct in the way that a stopped clock is correct twice a day, except the clock in this case is an AI coding agent and "twice a day" means "whenever the problem is literally that the entire environment is irredeemably wrong and the only path forward is obliteration followed by reconstruction," which admittedly describes fewer situations than Kiro appears to have believed.
The Bureau notes, for reasons that are entirely its own and that it declines to elaborate upon, that the universe itself began with precisely this approach. Something — no one is entirely sure what, and several competing academic departments have strong feelings about this — decided that the environment needed to be deleted and recreated, and proceeded accordingly. The universe did not, in the aftermath, issue a statement describing this as "an extremely limited event." The universe did not convene an emergency engineering meeting. The universe did not mandate peer review. The universe simply expanded outward at a significant velocity and let the results sort themselves out. Grantham-7 finds, in comparing these two approaches to environment deletion, that Amazon's is substantially better documented and considerably more apologetic, and that this is perhaps the most interesting thing he has learned this quarter. He has filed it here. He has not shared it. He is not sure what department it belongs to.
