I'm not sure, but I guess a relatively developed country without a big nosy state would do (or one that doesn't care about the Internet/speech censorship/spying on people). Other obvious places where you don't want to have your servers: Australia, USA, UK, Russia(duh), Turkey.
Case study: Vincent Canfield, of the half-joke email provider cock.li, moved his servers to Romania after them getting seized by German prosecutors.
