Post-Quantum DNS and TLS: What ML-DSA Means for Your Site

Short summary

Cloudflare is pushing for early adoption of ML-DSA, a post-quantum signature standard, and shipped new DNSSEC error codes after a TLD outage. The real near-term risk for most sites is DNSSEC misconfiguration, not quantum computers. Practical advice: keep TLS 1.3 current, let post-quantum key exchange happen automatically, and only enable DNSSEC if it's managed for you.

• •ML-DSA is a NIST post-quantum signature standard; adoption is happening at the host/browser layer
• •The biggest real-world risk is DNSSEC misconfiguration, not quantum decryption
• •Keep TLS 1.3 current and choose providers already moving on post-quantum crypto
