HTTP 103 Early Hints
InformationalAn interim response that lets the server send Link headers (preload/preconnect) before the final response is ready, so browsers can start fetching critical assets earlier.
Defined in RFC 8297
Common causes
- Server or CDN configured to emit early hints while the origin renders

Nothing to fix — it is a performance optimization
Ensure clients that can't handle interim responses ignore it gracefully
