The external servers are like cloudflare and fastly. Private relay doesn’t make any claims to be as private or anonymous as tor. It’s designed more to keep ISPs less aware of your browsing history and prevent websites from tracking you with IP. In my experience so far, Private Relay just turns off and back on randomly. There’s no safari indicator that private relay is off, just push notifications to inform you of the status. Private relay and mail privacy protection also completely disable when using another VPN. That said I’m very happy to get private relay with iCloud+ as it means phone is approaching the point where carrier can’t associate me with browsing history for to sell to whatever creepy business offers them money.
