I'm afraid you have to wait until it's not.
There are many problems that occur with League of Legends while logging in. The most common is that the server is busy. To fix this, try to login again. If it doesn't work check the LoL Support Page, provided in the Related Links area of this question.
There are no cheats for League of Legends. The closest thing to a "cheat" was the Konami Code. (Which is now changed). When you are in the launcher (the window that says if the servers are Online, Busy, or Unavailable), if it says Busy or Unavailable, press: Left, Right, Left, Right, Down, Down, Up, Up, 3, 4 That's the Konami Code, with 3 4 at the end of it. If you press the combination correctly, it will show the servers as being online. You can then get into the Air window (the place where you queue up for matches, edit your masteries, etc.). This is local only, and will not actually get you onto the servers (they are Busy/Unavailable for a reason). This is used to test your own files while the servers are down. You still can edit your Runes and Masteries, and it will register the changes when the servers come back online. Another one is pressing Ctrl+L and type in javascript:setServerStatus(1) This is the closest thing to a cheat in League of Legends. There are no cheats because the game is server based. Editor addition: You can also type in "thereisnourflevel" if your client is showing Busy/Unavailable. This will make the server status go online.

As we all know, Aunt Arctic is the newspaper writer of club penguin. Logically, she'll be a very busy person. But sometimes she takes time out to come on club penguin. However, even when she is online she is very busy interviewing people and taking reports for her newspaper. So, she would always be moving around room to room and server to server. So its almost impossible to tell you in one answer where she is, because by the time someone might have posted the answer to such a question, she might have already moved! So the best way to find Aunt Arctic is check crowded servers in rooms she could be when she is online.
