Automatically Secure: how we upgraded 6,000,000 domains by default to get ready for the Quantum Future

What this post added

This post details the implementation and results of Automatic SSL/TLS, a system that automatically scans and upgrades origin server TLS configurations to the most secure mode supported. It explains the technical evolution of TLS, the challenges of securing the edge-to-origin connection, and the mechanics of how Automatic SSL/TLS works by crawling websites, comparing HTTP/HTTPS content, and checking TLS certificates. It highlights the improvement from the previous SSL/TLS Recommender, which had low adoption, to an automated system that has secured over 6 million domains.
