8ch.net is using cloudflare.com DNS servers (where you browser go to figure out which IP address to use when you hit 8ch.net).
They all resolve to same same set of addresses, except from the Turkey and Russia pops
Network block 104/8 (any ip address under 104.0.0.0) is assigned to Cloudflare too
Traceroute shows a lot of GTT hops, but that's expected as they are a large backbone provider
That means only one thing: we connect to port 443 on this very specific address inside Cloudflare and that's from where we get the page (or post comments).
Beyond this entry point (under the hood) anything can be happening. The Cloudflare server could simply be a thin proxy and the real deal, which sits behind it, stays wherever it needs to be.
