I can not get into servers

Well I bought the game but when I go to play I select the server to log in but not enter it is loading in and out and not back to the home screen that I do (translation by google translator) I do not speak English

Portoguese:

bom eu comprei o jogo mas quando eu entro para jogar eu seleciono o servidor para logar mas nao entra ele fica em loading e nao sai e volta para a tela inicial o que eu faço (tradução feita pelo google tradutor) eu nao falo ingles

It is due to Ddos attacks (deliberate denial of service) so the servers are down for the time being. Hopefully back up soon!
