[tor-relays] Hidden Service on several relays + same .onion

Hey all,

Thinking about having fun with hidden-service webhosting on few relays.

If I'm not wrong : Host DNS name .onion of a server is stored in the file /var/lib/tor/hidden_service/hostname, there's another file private_key...

So my idea is to host the same website on 2 relays with different WAN IP, fingerprint, etc....... But if I copy those 2 files "hostname" + "private_key" on 2 or 3....... relays, will it be ok ? With this set up, if 1 relay is down, the 2nd can be reachable with the same .onion DNS name ? Will this failover method work, or will be it a mess with 2-3 relays with the same .onion name ?

Do someone have tried this ?

Thx all!
