But you do know the approximate speed of light in a vacuum?
there's always dark in my vacuum, so the speed of light doesn't apply there.

More importantly, what is the speed of light in a fiberoptic connection?
Speed of electrons in copper wire?
speed of electrical field, which is the same as speed of light.
electrons are much slower.
however, the longest distances on earth are about 20000km, which requires
at least 67ms for signal to get there and 133ms to get back.
in reality there's some small delay on each network device in the path, so
the 3ms can only be achieved on short distances.
