What's wrong with the official servers? I'm pretty sure they are 24/7.
Anyway, to do your own you'd have to reverse engineer exactly how theirs work, create a clone that works in the almost exactly the same way, then hack the game to connect to a different server (probably an Ocarina code or something like that). Seems a lot of work for little benefit. Unless your servers are going to be somehow superior to the official ones, no one is likely to go through the hassle of loading games through Gecko OS or Riivolution every time, just to play on your servers. And therefore there will be hardly anyone on the servers. And therefore no one will want to play on them because it'll take ages to get enough people to play a game. And so even less people would go on the servers.
If you have some big reason for wanting it, it'd
probably be possible, but it'd be a lot of work, and I personally cannot see the benefit.
