^^^^^^^^^
The "delete all" in ppp.linkup should have zapped this route :-(

I'm based in the UK and get lousy throughput most of the time to
anywhere in the US. 1k/sec is about expected, and interactive
traffic is a joke. But to my ISPs ftp machine, I get about 4k/sec.
This indicates to me that my ISPs routes to the US aren't fat enough,
but I haven't looked into it yet (it's been like this for a number
of months now, but was fine before).
I'm surprised with the upload timeout. Is this the norm ? Are
things better with pppd or with other OSs ? You could try removing
the Predictor1 deny/disable lines. There should be no problems there
these days.
