Why this matters for the Core Web Vitals, and where to start fixing it

An LCP image on a third-party domain pays the connection tax at the worst possible moment. The DNS lookup, TCP handshake and TLS negotiation for that domain happen before the first byte of the image arrives. The same image on your main domain rides the connection that is already open.

Third-party also means someone else's cache rules and someone else's outages under your most important resource. Self-host the hero if you can. If an image CDN must serve it, preconnect to that domain so the setup happens early instead of inside the LCP.
