Contact your hosting! :)
Or try:
file_get_contents('http://api.stackoverflow.com/1.1/search?tagged=php');
// Most likely it's also blocked.
You can also try to download with streams.
Or use sockets and connect directly to server and send a HTTP request and parse the response yourself.
There are ways, don't know if they work on your setup... if cURL is not available.
