Challenges of Cloudflare AKE Introduction on Multi‑Source TLS Configuration Compatibility and Latency Transparency
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.
Pain points
- Maintaining accurate key‑exchange preferences under diverse TLS configurations across multi‑source sites
- Lack of visualization for additional lookup latency, causing uncertainty about actual latency
- Dependence on Cloudflare's monopoly over the latest protocols and cipher suites, making it difficult for independent servers to obtain equivalent features
Questions to verify
- Does variation in TLS configurations across multi‑source sites lead to increased actual latency?
- Are users concerned about Cloudflare's exclusive control over the latest protocols and its impact on an open ecosystem?
- Is there a need for an open standard that can uniformly manage key‑exchange preferences in multi‑source environments?

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?
