## AI overview

This post-mortem explains an infrastructure incident that caused intermittent 404 responses when users downloaded Node.js or accessed parts of nodejs.org. Cloudflare cached incorrect 404 responses, an overloaded origin server returned 404s for valid files, and a build script bug triggered frequent rebuilds and cache purges after the migration to Next.js. The team fixed the configuration and reduced origin load, with the incident fully resolved on March 17.
