Abstract	In June 2025, Google Cloud Platform (GCP) suffered a major outage that disrupted services around the world. Over 50 key services were affected, including Identity and Access Management (IAM), API Gateway, BigQuery, and third-party apps like Spotify, Discord, and Cloudflare Workers. The root cause? A flawed automated quota update that stripped key API permissions. This paper breaks down what went wrong, explains the failure using a smart-home analogy, and outlines practical engineering steps to prevent such incidents in the future.
