Just to give you more insight. Google knows which IP address I am using Gmail from. If I use 8.8.8.8 they know what other content I am looking for which websites I visit and tie that to my account. If I use something like Cloudflare who do not expose my IP (or range) then I achieved more privacy. I could use my local DNS server (like I do at home) but I travel a lot.
In this case "misconfiguration" is actually for privacy and archive.is could live with that just like other sites but they intentionally screw with Cloudflare (aka the users who has 1.1.1.1 as the resolver).
