http://neverssl.com/online/ seems to work for me?
Are you perhaps on an untrusted network which is spoofing that url to make it redirect somewhere else?
http://http.rip/ is one I use
My browser (iOS safari) just takes me to the ssl version from that link, so “never ssl” seems wrong?
No, NeverSSL changed to have SSL a while back - around the time that Chrome/Firefox started throwing big warning signs and/or blocking non-https pages.
