Looking for a server, help me out pl0x.

I'm looking for a vanilla server with little to no rules that centers around survival, preferably on hardmode with pvp enabled.
I play on 2b2t but the connection sucks and the server's always going down or being attacked, so I'd like to have a back-up.
I just enjoy the challenge of hiding/protecting my base from other players.

I am aware that there is a sticky with servers listed, but I didn't see any that really appealed to me.
