Unity Network example question

I tested it downloaded from here unity3d resources.

So, when I click loader scene,

I clicked start server.

Then, it seems to be connected to unity3d server?

  1. How can I change that to 3rd server or my own server?

  2. What need to make own server? Mysql and php? and homepage?

  3. If launch game on facebook, where master server must be? Facebook provide game server too to developer’s game?

3-2, if not, how to make server for storing user’s game data? All is developer’s work?

Thanks for read and answer.

1/2: Master server build page
You can either host it on a VPS, or at home.

If you don’t like that, you can use the php master server hanging around the forums somewhere.

3:No, only Unity has a public master server as far as I know.
