DOGFOODING AT SCALE: MIGRATING CDNJS TO CLOUDFLARE'S DEVELOPER PLATFORM

Summary from the TLDR DevOps newsletter

Cloudflare has migrated cdnjs, a free JavaScript and CSS CDN used on roughly 12% of all websites, to run entirely on its Developer Platform as of June 23. The service handles an average of 108,000 requests per second across more than 330 data centers, with a 98.6% cache hit rate. The new architecture replaces a hybrid setup spanning GCP Functions and a VM, with R2 now serving as the single source of truth for file content and Cloudflare Workflows running the publishing pipeline.
