Ship Fast, Break Nothing: Auto-Rollback with Cloudflare workers

Francois Le Pape
Contentful
Abstract

In this session, I’ll walk through a production rollout system that combines versioned deployments, gradual traffic ramps, error-budget-aware gates, and automatic rollback on the Cloudflare Developer Platform. We’ll cover the hard parts: defining trustworthy signals, preventing flappy rollbacks, and handling emergency bypass paths safely.
You’ll leave with concrete patterns to increase deploy frequency while reducing risk and MTTR.
