+ Does my browser support HTTP/3 & QUIC?
+ +When loading this page from Cloudflare's edge network, your browser used HTTP/3.
+This page is HTTP/3 & QUIC enabled. Try reloading a few times to spring it into action.
+Not all HTTP clients have HTTP/3 & QUIC support configured. See our documentation for more information about how to check and configure your favorite client such as Chrome, Firefox or curl.

+ New to QUIC?
+ +QUIC is a new transport protocol being developed in the Internet Engineering Task Force (IETF). It offers reliability, security and multiplexing by default.
+HTTP/3 is a new version of HTTP that sits on top of QUIC. It leverages the new transport features to fix performance problems such as Head-of-Line blocking. This enables web pages to load faster, especially over troublesome networks.
+If you’re new to QUIC and need to learn more about the protocol, the following resources will help you gain a better understanding.

+
+
+ 
+
+
+
+
+
+ Faster handshakes
+ +QUIC handshakes are faster by design when compared to the equivalent TCP & TLS.
+Since QUIC uses TLS 1.3, it can benefit from zero roundtrip time (0-RTT) connection resumption. Check out our 0-RTT blogpost to understand more about this feature.
