It's a fake CAPTCHA. No matter how many times you pass it'll make you try again. It's tarpitting you because you're using some technology to increase your privacy, such as iCloud Private Relay or Cloudflare's DoH, and the operator of archive.today is opposed to privacy.

Cloudflare DNS and archive.* have a disagreement.

iCloud private relay breaks it. “Show IP address” in safari generally fixes it

same. hasn't worked in about 2 months.

Connect to a VPN & try different browsers until you can get past the captcha in one of them. If I can't get past it in 2 tries, I switch to a different VPN server.

*reposting workaround:

CloudFlare is in the right. This is for privacy. No location info sent.

Just put the IPs on your hosts file, it's easy. https://dns.google/query?name=archive.today

41.77.143.21 archive.today

41.77.143.21 archive.is

41.77.143.21 archive.ph

While there try a hosts blocklist
