Challenges of Cloudflare AKE Introduction on Multi‑Source TLS Configuration Compatibility and Latency Transparency

Updated 9/21/2026, 13:20:01

Problem

Cloudflare reduced HelloRetryRequests from 52% to 3.7% with AKE, but users note that the optimization does not publicly disclose actual latency, fails to maintain accurate key‑exchange preferences across multi‑source sites, and raises concerns about protocol‑stack exclusivity that Cloudflare controls, potentially hindering broader adoption and prompting demand for alternatives.

They are saving on the *possible roundtrip latency, however they are not sharing the absolute lookup latency which now gets added to every connection

Ever since http2 and especially http3 (my god did that take years to reach the mainstream), I've been sad to see intermediaries like Cloudflare gobbling up all the newest protocols and ciphersuites and etc while open source lags behind.

I'm curious how Cloudflare keeps the learned key exchange preference accurate when a hostname is backed by multiple origins with different TLS configurations?
