This is incredible. How did you find these certs?

I only noticed the star net one (not sure if it’s even in use) when writing this. I noticed the Pyongyang Zoo (which shares an IP with the Architects Society—one on 443 and one on 80 lmao) first, just from flipping through their very small IP space on Shodan.

You can see them all on crt.sh, because LE has to upload them to a CT log for browsers to trust them. (That’s how most of those subdomain finder websites work too.) The email servers seem to have gotten certs from a for profit CA back in 2015, but I’m not sure if they ever used them. Most of their webspace seems to be HTTP only. (And it’s a good thing, because some of their Apache versions are potentially old enough to have Heartbleed.)

The architects website has some pretty cool PDF magazines btw. They also have several websites for their insurance company’s (perhaps some intl org needs them to have a website for listing)—that’s a core hard currency stream for them and they previously have been accused of submitting false losses.
