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??)

Yes and yes.

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.
