Hi there,

Actually we tracked it down to router on Above Nets network. The clue was
when I pinged it from my home DSL it was fine. So I did trace from work and
then traced back to all the hops one at a time till I found the bottleneck.
It has since been fixed...

The moral of the story - t'aint the hardware, never is!

But I don't want to go among mad people,
Alice remarked.
Oh, you can't help that, said the Cat:
we're all mad here. I'm mad. You're mad.
How do you know I'm mad? said Alice.
You must be, said the Cat,
or you wouldn't have come here.
