HTTP/3 (QUIC) active - modern transport in use
HTTP/3 is the latest version of the protocol that browsers use to request pages and files from your server. It is built on a faster underlying technology called QUIC, which establishes connections more quickly and handles poor mobile network conditions better than older versions. Your server is advertising HTTP/3 support.
Why this matters
This is a positive finding. Browsers that recognise the signal upgrade automatically, saving 50 to 150 milliseconds on every new connection - a meaningful improvement for mobile visitors on variable networks. You are in the top tier of sites for transport performance. Keep it up.
How to fix it
No action needed. Ensure your hosting provider or CDN keeps HTTP/3 enabled as you make infrastructure changes, and verify the setting is preserved after any server or proxy upgrades.
