Fastly offers everything you need from a modern CDN, from effortless scale and built-in security to programmable control and full visibility.
The next version of the internet is here.
HTTP/3 and QUIC
Web browsers, web servers and other critical pieces of web infrastructure are getting support with this new standard. This is the modern version of HTTP, which web browsers use to communicate with web servers and send data back and forth.
Modern protocols
Performance, security and flexibility for the modern web.
The benefits of HTTP/3 and QUIC are most evident for businesses that rely heavily on mobile users, or have customers in parts of the world that have spotty internet connections.
Deliver a better experience globally
Web traffic flows faster because it’s designed to avoid head-of-line blocking and offers a low-latency handshake that significantly reduces rebuffering.
Secure more with built-in encryption
TLS 1.3 - the latest version of the Transport Layer Security protocol - is built directly into QUIC. This design more effectively secures headers and metadata from third parties, ensuring more private, trustworthy connections than ever before.
Integrate deeper to innovate faster
Because QUIC runs in userspace, it integrates seamlessly with Fastly’s tooling, tracing and logging infrastructure. This makes it easier for developers to run and learn from experiments, enabling more rapid deployment and evolution of sites and apps.
Features
Latest version of the internet
Explore the key features and how they are enhancing the performance, security and reliability of internet communication.
Faster connection establishment
QUIC's handshake is much faster, as it combines the initial connection setup and encryption handshake into a single step, reducing latency, especially for users connecting to a server for the first time.
Enhanced security
HTTP/3 ensures that data exchanged between the client and the server remains secure and protected from attacks. HTTP/3 uses TLS 1.3 for encryption, which is the most up-to-date and secure version of the Transport Layer Security protocol.
Improved reliability
QUIC includes built-in mechanisms for detecting and recovering from packet loss or network congestion more efficiently. When a packet is lost, QUIC can retransmit only the lost packet while preserving the order of the other packets, ensuring a smoother browsing experience, even on unreliable networks.
"94% of browsers already support HTTP/3 and here at Loveholidays we like to be on the cutting edge so when our CDN partner Fastly enabled it, we decided to give it a go. Loveholidays is 18% faster with HTTP/3."
