my suggestion would be to ask cisco what isp they recommend
for dialup access from your location, and dial in through them.
you should be able to lop off 60% of your hops and probably 99%
of your problems if you pick right.
You're transiting two NAPs (MAE-WEST and the DEC exchange (?)) which
both provide service that's essential on one hand (wide access to
the greater Internet) and lousy on the other hand (focussed access
to a particular site).
If you want good internet service to a particular point on the network,
you must shop for it specifically and be prepared to continue to shop
for it whenever the underlying network topology changes.
