End of the road for RC4

What this post added

This post details the complete disabling of the RC4 encryption algorithm for all SSL/TLS connections to Cloudflare sites. It explains the phased approach taken over the past year, including disabling it for TLS 1.1 and above, and then deprecating it. The post highlights the remaining use cases for RC4 (old mobile phones, Windows XP, and SSL-intercepting proxy software) and the rationale for its complete removal due to security vulnerabilities, even for the remaining small percentage of connections.
