HTTP/3, the newest evolution of the Hypertext Transfer Protocol, and QUIC, the new, always-encrypted transport protocol, are now supported by Fastly’s edge cloud platform. Together, these foundational standards improve our network from the inside out and help you deliver excellent digital experiences all over the world.
Is your browser running on HTTP/3 and QUIC right now? We built http3.is to help you find out.
QUIC allows web traffic to flow faster because it’s designed to avoid head-of-line blocking and offers a low-latency handshake that significantly reduces rebuffering. These innovations modernize the internet and improve digital experiences for all users, but especially for mobile users and those around the globe with less-than-reliable internet service.
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.
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.
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 with unreliable internet connections. Performance enhancements are greatest for companies in the following industries:
Gaming
Streaming media
VoIP and video conferencing
Saas and Paas
Fastly can help you enable HTTP/3 and QUIC within our edge cloud platform. Join the beta or, if you’re already a Fastly customer, reach out to your support team to have them enable HTTP/3 and QUIC for you.

HTTP/3 and QUIC were designed with the future in mind — more responsive, secure, and flexible than the standards that came before it. Here are just a few design features that enable the protocol to modernize the web:
Built on top of UDP to solve for head-of-line blocking.
Incorporates TLS 1.3 for shorter handshakes, lower latency and rebuffering, and always-on encryption.
Runs within userspace and built with open standards to allow for future evolution.
Fastly engineers have been part of the team designing QUIC for the better part of a decade, giving us a unique view of the immense value QUIC brings to our customers, and the internet at large. Dig into the details with blog posts and talks straight from the minds of some of QUIC’s creators.
