Major Milestone: Majority of Human Traffic Uses PQ TLS

🔒 Cloudflare reports that, as of late October 2025, the majority of human-initiated traffic through its network is protected with post‑quantum key agreement, reducing the risk of harvest‑now/decrypt‑later attacks. The post summarizes progress since the last update 21 months earlier: NIST standardization, broad adoption of ML‑KEM hybrids, Google's Willow milestone, and Craig Gidney's optimizations that materially moved Q‑day closer. It explains why migrating key agreement was urgent and relatively straightforward, why signature/certificate migration remains the harder challenge, and what organizations and regulators should prioritize now.

Automatic SSL/TLS: Upgrading 6M Domains for Quantum Safety

🔐 Cloudflare's Automatic SSL/TLS now upgrades origin-facing encryption by default, having strengthened over 6 million domains without operator intervention. The system scans origins, verifies content and certificates, then gradually ramps stronger SSL/TLS modes from 1% to 100% of traffic, aborting safely on failures. This prepares sites for the post-quantum era by favoring hybrid key agreements (X25519 + ML-KEM) and will soon automate post-quantum handshakes and ad-hoc rescans.
