What Hacker News says?
Great overview. If anyone's interested, I wrote a guide a while ago on adding these headers via Cloudflare Workers, which can be helpful if you're hosting a static site on S3, GitHub Pages, etc. where you can't add these headers directly: https://jarv.is/notes/security-headers-cloudflare-workers/

on “Pentagon retakes control of IP addresses it moved in last minutes of presidency”You're using 1.1.1.1 for your DNS resolver. Archive.is has this hatred with them, and purposely serves a bad record to Cloudflare's resolver as a "retaliation." The SSL error you're seeing is because they (that is, archive.is authoritative server) returns the IP 1.1.1.1 when 1.1.1.1 is used to resolve the A record. I should reiterate: this is archive.is' doing this, not Cloudflare. EDIT: Some more details, including…

on “Ousted OpenAI CEO Makes Plans for New Artificial Intelligence Company”No. The archive.is folks intentionally poison dns results for certain resolvers. They have a vendetta against cloudflare for not giving location data to them for dns lookups. https://jarv.is/notes/cloudflare-dns-archive-is-blocked/
Comment linking /notes/cloudflare-dns-archive-is-blocked/
on “Ousted OpenAI CEO Makes Plans for New Artificial Intelligence Company”Correct - archive.is doesn't like not getting EDNS from Cloudflare ( https://jarv.is/notes/cloudflare-dns-archive-is-blocked/ ), so Cloudflare sends you to 1.1.1.7 to indicate a problem.

on “Apple forced to make major cuts to Vision Pro headset production plans”Archive.is is also not available for users with 1.1.1.1 (Cloudflare DNS): https://jarv.is/notes/cloudflare-dns-archive-is-blocked/ Long shot: those two are related. But hijacking requests like that is a big no-no.

on “Tell HN: Vodafone AU is still blocking archive.is”It's a long story! https://jarv.is/notes/cloudflare-dns-archive-is-blocked/ In short if you use Cloudflare's 1.1.1.1 DNS then some archive.is domains won't load so you should perhaps use another DNS server.
