I had problems connecting to web pages over wifi from my Android phone yesterday evening, and again this morning. I couldn't ping news.bbc.co.uk - the ping request returned "unknown host". I know it was a problem with BT DNS, because other boxes on which I can use OpenDNS worked fine. At the moment it seems to be working.
My question is, what's the best way to make BT aware of this, if they're not already? I wasted a lot of time on their live chat app; I might as well have been speaking double Dutch as far as the woman on the other end of the line was concerned.
