Google Cloud's Massive Outage: A Simple Code Error's Catastrophic Impact

Last week's massive Google Cloud outage, lasting several hours and affecting numerous clients including Cloudflare, stemmed from a code change in the "Service Control" component of Google's API management control plane. The new feature lacked proper error handling and feature flag protection, leading to a null pointer exception. This triggered a cascading failure upon a specific policy change, overloading the infrastructure. Google admitted insufficient error handling and monitoring, promising improved external communication and internal processes. However, the incident highlights the vulnerability of even tech giants to large-scale outages.
