I'm not sure if anyone else uses BTs News Server to get here but I
found a problem yesterday that I thought I'd better share just in case.
Turns out that not all of BTs IP addresses can access their News Server
so if, like me, you have occasion to turn off your connection and
restart you may be given a new IP address that stops you getting to the
Server. You get 480 Server requires authentication. Took me to turn it
off and on again 3 times before I could connect again!

Not experienced that, but nice to know just in case.
