Firefox said Cryptome wasn't using TLS1.3, asked to try TLS1.0/1.1, that worked. Found a couple old URLs needed updating.

The archive [https://cryptome.org/cryptome-archive.htm] goes back to 1997, is available on media.

This site is older than Wikileaks. It’s been down for a few months. I’m concerned about John Young.

eh? it's up. works for me - screenshot:

My first thought was exactly as the parent comment, but the site and links load fine for me too. It's been a while since I've visited. I still hope Mr Young is well.

Edit: there are 5 posts for March 2022. A good sign.
