Crumbs, it's kept working for 5 consecutive minutes ...
When it works, it's fine, as you can see:
But when it doesn't, it either drops the internet connection (whilst leaving the actual DSL connection intact), or else it drops and immediately reacquires a duff connection. Any idea what causes this sort of thing?
Incidentally, VM's ADSL service status helpfully claims there are no problems.
