> 8.8.8.8 e 8.8.4.4 vc quer dizer neh?! (4.4.4.4 nao existe, hehe)

Existe o 4.2.2.2, mas com latência mais alta a partir do Brasil.
Fiz pesquisas nos 8.8.8.8, 8.8.4.4 e 4.2.2.2 para aumentar a chance de
estar no cache (o que em cluster nem sempre resolve) e então refiz as
pesquisas, e deu isto aqui:
