Key Points
- Two Kiro incidents were traced to user error and permission issues, not AI faults.
- The first incident was an “extremely limited event” affecting a single service in mainland China.
- The second incident had no impact on a customer‑facing AWS service.
- AWS introduced mandatory peer reviews, staff training, and tighter access controls after the incidents.
- Kiro now requests authorization before taking any action by default.
- AWS targets 80 percent of developers using AI for coding at least once a week.
- Some employees remain skeptical of AI tools due to error risk.
- The events follow a major 15‑hour outage in October 2025 that impacted services like ChatGPT.
- AWS reports strong customer growth for Kiro and emphasizes efficiency gains.
Background
Amazon Web Services (AWS) launched Kiro, an AI‑powered coding assistant, in July. Designed to move beyond rapid‑build tools, Kiro writes code based on detailed specifications, aiming to boost developer efficiency. AWS also previously relied on its Amazon Q Developer chatbot for code assistance.
Incidents Involving Kiro
Two separate events highlighted challenges with the new tool. In the first case, described by Amazon as “user error, not AI error,” an “extremely limited event” impacted a single service in parts of mainland China. The second incident, also attributed to user error, did not affect a “customer facing AWS service.” Both situations stemmed from engineers having broader permissions than intended, a user access control issue rather than an AI autonomy problem.
Company Response and Safeguards
After the December incident, AWS implemented several safeguards. These include mandatory peer review of changes, enhanced staff training, and stricter permission controls for AI‑assisted actions. By default, Kiro now “requests authorisation before taking any action,” reinforcing human oversight.
Employee Sentiment
Some AWS staff remain skeptical about the utility of AI tools for the bulk of their work, citing the risk of error. Nevertheless, the company has set an internal target for 80 percent of developers to use AI for coding tasks at least once a week and is closely tracking adoption rates.
Broader Context
The incidents occurred against a backdrop of a previous 15‑hour AWS outage in October 2025 that forced multiple customer applications, including OpenAI’s ChatGPT, offline. AWS reports strong customer growth for Kiro and emphasizes the potential efficiency gains for both customers and employees.
Future Outlook
With the new safeguards in place, AWS aims to balance rapid AI‑driven development with robust safety measures, hoping to increase confidence among engineers while expanding AI adoption across its cloud services.
