If we’re talking takedown-resistance, we may need to enter the dark web realm:

• Tor hidden sites are inherently hard to pinpoint
• ZeroNet was an interesting project, seems to be abandoned
• I2P is like Tor on steroids, can publish all sorts of services
• IPFS is a decentralized P2P storage system (best/worst known for NFTs)
• FreeNet Hyphanet is a 25+ years old distributed content system with limited support for services
• FreeNet is… honestly, haven’t seen a working example, but it sounds interesting?
• Matrix… if they manage to get things under control
• Nostr is a censorship-resistant distributed messaging system

Hosting distribution and localization varies, but they all have features to make it hard to pinpoint host and/or client locations.
