tl;dr: No. Quite the opposite, actually — Archive.is’s owner is intentionally blocking 1.1.1.1 users.
CloudFlare’s CEO had this to say on HackerNews:
We don’t block archive.is or any other domain via 1.1.1.1. […] Archive.is’s authoritative DNS servers return bad results to 1.1.1.1 when we query them. I’ve proposed we just fix it on our end but our team, quite rightly, said that too would violate the integrity of DNS and the privacy and security promises we made to our users when we launched the service. […] The archive.is owner has explained that he returns bad results to us because we don’t pass along the EDNS subnet information. This information leaks information about a requester’s IP and, in turn, sacrifices the privacy of users.
I am mainly making this post so that admins/moderators at BeeHaw will consider using archive.org or ghostarchive.org links instead of archive.today links.
Because anyone using CloudFlare’s DNS for privacy is being denied access to archive.today links.

Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

There’s a comment on one of the HN threads that gives a little more insight - basically it helps him combat abuse by routing requests to the closest server outside of the requesting ips area: https://news.ycombinator.com/item?id=36971650
Not sure how that argument really holds up to scrutiny but it’s something.
Oh, so he’s not using a CDN, but a sort of “anti”-CDN.
Wonder why 😆
Yes, that holds up to scrutiny pretty well.
…and that’s a dick move on part of CloudFlare.
