Problema con copy()

[albarete]

Tengo:

Código JPHP:

<?php 
$pre = "http://api.erepublik.com/v2/feeds/countries/15/citizens.xml.gz";
$o = copy(($pre), "/es.xml.gz");
?>
 

Y me da dos errores :S :

Warning: copy() [function.copy]: php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in /home/a9268525/public_html/index.php on line 9
