That said, I have the same problem. Even hard coding the IP address I resolved through Google doesn't seem to work. I'm guessing their sabotage may have backfired and is causing issues beyond their intentional scope?
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.
