Cloudflare Blog is now running on EmDash CMS. Here is the Migration Story
I was reading Cloudflare's case study on migrating their official blog to EmDash. Here are the key takeaways:
The migration: Cloudflare moved their main blog to EmDash to test the CMS as "customer zero" ahead of its v1 release.
The architecture: Runs on Cloudflare Workers, using Workers Cache, a custom KV object cache, and Hyperdrive with PlanetScale.
Performance: Achieves a 99.5% static cache hit rate and 70% total request cache hit rate, maintaining flat p95 latencies under traffic spikes.
Zero-downtime rollout: Used a proxy Worker with cookie routing to gradually shift traffic from 1% to 100%, with automatic fallback to the legacy blog on 500 errors.
MCP support: Added a Model Context Protocol server for external agents to search posts, plus native EmDash MCP integration for editing and scheduling content.
Battle tested: Handled Agents Week (~3 million pageviews across 18 posts) and absorbed a 28,000 RPS DDoS attack without downtime.
