Gonna go out on a limb and agree with the archive.is owner -- the reason he blocks it is bc cloudflare intentionally doesn't support edns client subnet. They cite privacy reasons, but it comes at the at the cost of performance -- most cdns use DNS based routing, so using cloudflare DNS means you connect to random server for a lot of websites. CloudFlare on the other hand uses anycast routing for their CDN, so they don't suffer at all.
I hate Google but my pihole is configured to use their DNS resolvers. Lesser of two evils.
