Are you using a FRITZ!Box ?
If so have you got another different branded router to try.
The FRITZ!Box sometimes detects the BQM as a possible ICMP Flood Attack and then blocks it, this is a good feature.
I had a similar issue a while back when I used an AVM FRITZ!Box 4040 where after 10 days of use it would look like your BQM until I rebooted it and it was fine for another 10 days.
I then moved over to another 3rd party router and the issue as gone.
Also when you say a ping to bbc.co.uk of 200, was that you did 200 pings or you got a ping of 200 to the bbc.co.uk ?
Not too sure how far you are from London, but a 200 ping to the BBC site is a bit high.
