Code Orange: Fail Small is complete. The result is a stronger Cloudflare network

What this post added

This post details the completion of the 'Code Orange: Fail Small' initiative, which significantly enhances Cloudflare's infrastructure resilience. Key technical contributions include the development of Snapstone for health-mediated configuration deployments, the implementation of 'fail stale', 'fail open', and 'fail close' strategies for reducing failure impact, and the segmentation of services by customer cohorts for blast radius mitigation. It also covers the revision of 'break glass' procedures with backup authorization pathways for 18 key services and the creation of a mandatory internal Codex, enforced by AI code reviews, to codify improvements and prevent regressions.
