Is this specific to Tor, or would it also affect CDN's? I am not a fan of commercial CDN's (for my own hobby sites) so I set up haproxy+strongswan VPN nodes in various VPS sites around the world, that cache and relay traffic to/from a few nodes in another VPS. For all intents and purposes, my websites are actually hidden, despite having public IP addresses and names. I've had front-end caching nodes in Germany before.
