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.
My point is that I should be able to expect better than a 40-percent loss rate to *any* point on the Net, at *any* time, from *any* provider. In fact, I think I should be able to expect less than 5 percent, and probably less than 1 percent. Back when I actually touched routers, I used to recommend that people upgrade their internal networks when loss rates hit 1 percent. A situation where I have to "shop around" for connectivity depending on what site I want to talk to that day is just plain unacceptable.
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).
It doesn't look to me as though the loss is being introduced at the NAPS. If you look at the trace, you'll see that significant loss starts to appear within Alternet, well after MAE-west. It looks as though more loss appears inside BBN's network, although it's difficult to tell because of the already large Alternet loss.
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.
Thanks for the suggestion, but I work for Cisco, so ordinarily I have a Frame Relay connectivity into Cisco's network. This week the computer I usually use for work is in for service. The Cisco LAN at my house is air-gapped from the personal LAN, and it would be a real pain to reconfigure everything, so for the moment I'm coming in to Cisco over the Net, using my personal service. It's purely temporary. If I did interactive work under these conditions on a regular basis, I'd have gone insane long ago. -- John B.
