Though the news may sound confusing to some, the Brazilian servers were, in fact, not located in Brazil, but in the United States.

“Evocator!
It is with great joy that I come to you communicate that the League of Legends servers, hosted in Brazil, are already functioning, and this morning we began the process of gradual transfer of games for the new data center. For this transition to be a period of adjustment and tuning, which can take several weeks, players can now go into matches with reduced latency. Over time, the frequency matches with old latency will decrease and finally disappear.
We have taken a great first step in our commitment to reduce latency in BR matches the platform, providing a better gaming experience to the Brazilians. But it is important to remember that many factors can influence the performance of the game: the quality of broadband in your area, access routes used by your internet provider, type of used connection (3G, wi-fi) etc..
I hope you enjoy the new and celebrate this achievement with us! Thanks for the confidence, patience and messages of encouragement throughout this process.
You are responsible for the great success of this game in Brazil and hope to share many more achievements in the coming years.
See you in the Fields of Justice!"
