Vercel CDN adds Encrypted Client Hello support

Vercel's Encrypted Client Hello rollout is a small changelog item with real privacy weight. SNI has long exposed the hostname a client is connecting to during TLS setup; ECH closes that gap where browser, DNS, and platform support line up.

The staged rollout is also a reminder that protocol upgrades depend on ecosystem readiness. CDN providers can hide a lot of complexity, but deployment still has to move region by region, TLD by TLD, and client by client.
