Why isn't phantom.js loading the page?

Question

JavaScript

Hello. Such a problem.
There is a server on ubuntu 14.04
Installed phantom.js Hello.js
script

console.log('Loading a web page');
var page = require('webpage').create();
var url = 'http://www.phantomjs.org/';
page.open(url, function (status) {
    //Page is loaded!
    page.render('/home/user/phantomjs.png');
    phantom.exit();
});

I launch phantomjs /home/user/hello.js for execution
The first output to the console works out. And then nothing. So the inscription Loading a web page hangs.
I didn't wait for the page to load. Either phantom.js does not load the page at all, or it loads very slowly.
How to deal with it?

Answer 1

remove www from the address... they have some jamb with the site with www, it resets by timeout)

Answer 2

What is the capacity of the server (ram, cpu)?
