XML parsing takes too long

hi, when i try to output the values within a xml from an url in a console window, it stucks at xml.Read(); for about 20 seconds, however, i sent the test build to a friend, and it only takes 1 sec for him, what could possibly be the cause of this prolonged delay?

code snip:

Code:

---

        string partialurl = "http://statapi.transformice.com/miceinfo.xml?n=";
        Console.Write("Name: ");
        string mousename = Console.ReadLine();
        string fullurl = partialurl + mousename;
        Console.Write("URL will be: ");
        Console.WriteLine(fullurl);
        XmlTextReader xml = new XmlTextReader(fullurl);
        xml.Read(); // Hangs at this location!
        xml.ReadStartElement("mice");
        xml.ReadStartElement("name");
        Console.Write("Name:  ");
        Console.WriteLine(xml.ReadString());
        xml.ReadEndElement();
