This just helped me realize why I couldn't get to archive.today anymore -- however, for me, both Google DNS (8.8.8.8) and CloudFlare DNS (1.1.1.1) resulted in either infinite captcha loop or timeout.

I had to switch back to my ISP DNS to have connection successful.

I did not realize that choice of DNS resolver could effect access to a website like this. I thought DNS was boring stable technology. The error conditions weren't even DNS failure (which I would also find surprising from Google or Cloudflare), but that server timeout, or weirder infinite captcha loop.
