If you are using Cloudflare for DNS you will run into that issue. It is by design.

One affects their DNS resolution of archive.is, GP is talking about Cloudflare's endless captcha portal on that site. Strangely enough, it works for me today, but a few days ago I couldn't get past that obnoxious screen.
I just wish people would stop flocking to Cloudflare and making the internet even shittier than it is.
The thread you’ve linked to isn’t very clear on its own -- it seems like it’s missing a lot of context.
The first reply makes it sound like archive.is is blocking Cloudflare, but it sounded like you meant the opposite.
(And I assume this is all separate from the CAPTCHA thing, as the other reply says)
