The server at www.netflix.com can't be found

The server at www.netflix.com can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network. Something like this happens on every browser and my PS3. WTF.
