I can pull the data just fine with:
$c = curl_init('https://btc-e.com/api/2/btc_usd/depth');
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt($c, CURLOPT_SSL_VERIFYPEER, false);
$html = curl_exec($c);
if (curl_error($c))
die(curl_error($c));
// Get the status code
$status = curl_getinfo($c, CURLINFO_HTTP_CODE);
curl_close($c);
echo "<pre>".print_r($html, true)."</pre>";
It prints this:

So I don't think I'm running up against the DDOS protection. I've been wracking my brain for 2 days and can't figure it out.
What version of php do you run? Maybe that has something to do with it?
