I couldn't get it to load from the ipfs.io gateway, nor my local ipfs daemon, but I could through cloudeflare's ipfs gateway.

It's also available at regular-old https://leotindall.com/
(not that that's functionally much different than the regular page, of course)
Being a total noob I enjoyed the article (thanks OP) then went on to wonder how this works. So first I thought it was available through all of these gateways, but then I read something about pinning - do the gateways pin the content? Or the "hosting nodes" (forgive my lack of knowledge about the terminology)?
