I think the site is under load and the kernel loading is timing out.

EDIT: Yeah, it can't transfer the files in time. It doesn't help that the image files are set to no-cache and the browser reloads them every time. I wish he had published it on IPFS.

I couldn't run it today, but I remember a few months ago it ran fine. The load hypothesis seems right.
