It was fine when I read the first five or so installments, then I got a random authentication request, which I couldn't see the cause of, but seems like it may have been triggered when I chucked an image. My guess is that during the time I was viewing the site, the owner decided they would lock it down to people who were authenticated. Shame as I was just getting to the point of progress!

Curious. Maybe it was hugged to death and he or his ISP locked it down to cut down on bandwidth. Or maybe decided he didn't want a bunch of people reading it right now?

It’s accessible via the Wayback Machine, fortunately.

The site was posted here and probably other social media in the last day or so. More than likely it's to prevent the site from getting hugged to death.

Prevent?
