Thanks, Roger. I so did, and got an interesting result. You can see
that as I work my way out, the ping time gets slowly longer, but on
the last one, it jumps from ~13 ms to ~88 ms. Does that seem unusual,
or is because it's going across a large way? I did ping a .co.il (my
country's domain extension) address, but that does not necessarily
mean that the site is hosted here.
