With respect that is not the reasoning. Cloudflare are intercepting access from some IPs and imposing a man in the middle dialogue before "granting" access to https://www.ietf.org/rfc.html e.g. This is the report I get below a captcha - CloudFlare Ray ID: 283f99aee908294a • Your IP: 93.115.95.206 • Performance & security by CloudFlare There may be other usability issues with the ietf site such as javascript use but that is a separate issue I think to having a traffic policeman standing permanently in the middle of the road. The question is does IETF need that policeman to do that filtering? Is it desirable? I don't get the sense that it is. Christian
