Am I misreading the big jump in time between 11 and 12 as transatlantic
traffic? LND2 does sort of evoke "London" the same way that DCA evokes
"Washington DC" (Tyson's Corners??)

And this, on the other hand, shows that you have no touble getting to Lugnet.
Since this trace also goes through UUNet's Tyson's Corners routers, and then
out to Pair's UUNet customer router in Pittsburgh, I would diagnose the above
dropped packets as meaning that cais.net is the sucky network.  I assume,
though you don't mention it, that you had not trouble getting to Lugnet on
several tries, and this was around the same time (and I mean within minutes)
of the trouble reaching Bricksmiths.

Yes and yes.

Of course, I have no idea what you think this proves about jump.cgi.  Unless
you're on Lugnet's servers, you can't pin down how long it takes Lugnet to
reach bricksmiths.com... but from the above, I wouldn't be surprised if the
slowdown was being caused by cais.net.

I have no idea what it proves about jump.cgi either, I wasn't asserting that
it proved anything in particular, I just wanted to give some data behind my
empirical in the post before it. (that a direct url deref took me 2 secs,
and a jumped deref, more like 6 or 7 seconds)

I will say this, I agree with your assessment about bricksmiths potentially
being behind a potentially bad connection and I will raise the point with
the Powers That Be. :-) Since we're getting it free, though, moving may not
be feasible. (and we're grateful, believe me).

I will say one more thing, and i think this is more important actually, than
diagnosing why bricksmiths is slow, I think we need to seek a different site
as the jump target for testing jump.cgi. Some site small enough that it's
not "secretly" multiple hosted like Yahoo is, but with a better connection??
I dunno.
