Why not? We don't run the Internet, we just connect people to it. And our
10Mbps fibre ATM link rarely gets to 25% utilization.

momentary samples such as yours are meaningless. One moment you can have
0% loss, the next moment 10%. I will agree that sustained high loss
levels are not acceptable, but isolated ping measurements do not measure
that.

I disagree. If you get busy signals or recorded messages from a telco
other than the one who provides your local phone service, the most they
will do is to promise you that they will look into it and/or inform the
company whose service appears to be the problem. This is all any ISP can
do when a customer complains that ISP X is not reachable or that ISP X's
site appears to be overloaded. I am talking about ISP's here, not NSP's.
