You will to check your apache's mod_security settings. This could be causing your 503 Service Temporarily Unavailable
Try adding the correct JSON header to your PHP file.
header('Cache-Control: no-cache, must-revalidate');
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Content-type: application/json');
