What it is

Binary, multiplexed successor to HTTP/1.1. One TCP connection carries many parallel streams; headers are compressed via HPACK.

Why it matters

Cuts page load time noticeably on multi-asset pages. Every modern CDN (Cloudflare, Fastly, CloudFront, Akamai) supports it by default — there's no excuse for not having it.

Who it applies to

Every public site.
