OK, well I am confused now. I thought that since tracert can't really ask
all the routers on the routing to report interroutter times, that what it
displays is the time from where the trace is run to that particular router,
one router after another... that is
the time from where I am to 10 is 10,10,10 MS over three tries
the time from where I am to 11 is 10,10,10 MS
...so probably almost instantaneous but you can't be sure because this
tracert actually ran different tests to get the node 10 numbers than it did
to get the node 11 numbers
the time from where I am to 12 is 80,90,90
... 12 is the first node on the other side of the atlantic.. or that it
takes 70-80ms to cross the atlantic (5-7 times the speed of light time for
that distance, more or less, so not that unreasonable)
and the times to 13, 14, 15, etc don't go up much (implying short node to
node times) till we get to the cais nodes...
or am I misunderstanding how tracert works?

| (...) No, you're right. I don't understand how you're confused. If it was my original assertion that it might have been the UUNet network that was causing the suck, well... You got how traceroute works completely right. But something to keep in mind (...) (24 years ago, 1-Dec-00, to lugnet.off-topic.geek)
