> https://archive.is is now serving, via Cloudflare

It looks like a cloudflare page but it's not hosted by them. eg. https://bgp.he.net/dns/archive.is#_ipinfo It's hosted by AS49505 JSC Selectel

To add onto this, cloudflare switched away from recaptcha a while ago. https://blog.cloudflare.com/moving-from-recaptcha-to-hcaptch...

I think they now use their own Cloudflare turnstile if I remember correctly, but back then they switched to hcaptcha.
