Are you by chance using Cloudflare for DNS? If so that would be the answer. Archive.is gives CF their own IP's back to them rather than the correct DNS answer on purpose. Some people will get endless captchas and some will get errors.

I switched Archive domains from Cloudflare DNS to Mullvad DNS on my unbound, haven’t had issues since. I also would recommend quad9 as a dns resolver, it doesn’t have an issue.
It resolves for me but shows a captcha loop as others said, strangely the captcha page I'm getting seems to be some mockup of the Cloudflare one, using reCAPTCHA which Cloudflare publicly spoke about switching from.<p>Seems to be doing something odd, code of the page includes some XmlHttpRequest to a blog site with randomized query string (see end of <a href="https://pastebin.com/W21Au8RK" rel="nofollow noreferrer">https://pastebin.com/W21Au8RK</a>), along with some fingerprint library (though commented out)<p>That blog site loads very slow for me if I go there manually - maybe some kind of DoS being directed to it?<p>Seen this same faux-cloudflare page used on btdig.com too, with the same strange XmlHttpRequest & fingerprint code, pretty weird.
The other day I was on hotel Wi-Fi and I got this recapture loop. I got off the Wi-Fi and went to mobile network and it came back. Are some ISPs blocking it ?
> Legal troubles?<p>Wouldn't be surprising - these services were basically stealing content from other sites and replacing original ads/tracking/spyware with their own.
