one more interesting fact i would like to put here is that if you host with a cheap based company then there are chances that your ip is blocked by some isps, so due to that the countries whose isp's have blocked the ip of that hosting company, their residents wont be able to access your site at all, without using a proxy server.

also, some hosting providers block certain countries like china, so even if their isp didnt block your server but your server blocked it then residents of that country couldnt access your site at all.

so in both cases above you loose potential visitors to your site, so always choose a hosting provider which doesnt block a country and whose ip addresses arent blocked by some isps of some countries.
