I was experimenting last night with a site I've visited a few times in the past and found I can no longer access it. It times out with the error;
Network Error (tcp_error)
A communication error occurred: "Operation timed out"
The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.
For assistance, contact your network support team.
If I use a vpn addon I have for my browser then I reach the site no problems.
Though I'm not using the default BT DNS server I am using one of their additional dns servers.
What's a good dns server people recommend outside of BT?
Demon => Freeserve => Pipex => Be => Sky => BT Infinity 2
