Sorry, but it's you.

That's because emtratell.com doesn't exist as a domain. The root nameservers know this and tell you immediately. The domain "embratel.com" does exist, and your request for the IP address of the "www" host is forwarded to their nameserver. Due to distance, or a lack of resources, the response from emtratel.com takes two mintues to come back. I'd guess it's a slow nameserver at embratel.com.
