The HTTP version of your URL works fine. The HTTPS version has an expired cert. If I click past that, it redirects to redis.io, then gives a 404.
I know antirez is a smart guy, but if this is some kind of "I'm taking a bold stance against HTTPS" then I'd rather read the archive.org link with functioning HTTPS. My threat model prefers trusting archive.org to correctly reproduce the blog, over trusting everyone between me and antirez.com.
