This may well be the problem:

HttpWebResponse myResp = (HttpWebResponse)myReq.GetResponse();

WebResponse implements IDisposable, so you should use a using statement for it (and for the StreamReader you create from the stream). If you leave a WebResponse open, it will take up a connection from the connection pool to that host, and you can end up with timeouts this way. The fixed code would look like this:

string responseString;
using (var response = myReq.GetResponse())
{
    using (var reader = new StreamReader(response.GetResponseStream())
    {
        responseString = reader.ReadToEnd();
    }
}

This will close the stream and the response even if an exception is thrown, so you'll always clean up the resources (in this case releasing the connection back to the pool) promptly.
