right
where
most
of
the
online
services
and
connectivity
providers
run
their
systems.
Moreover,

scientific

Other
Internet
speed
tests
you
may
find
online,
typically
measure
the
speed
between
you
and
the
service
provider’s
network.
We
call
this
approach
a
“last
mile”
test.
It
is
a
valid
approach
to
verify
that
your
provider
is
honoring
the
speed
promised
in
your
contract.
But
it
doesn’t
tell
the
whole
story
on
how
fast
you
can
watch
movies,
send
large
attachments
or
make
HD
video
calls
with
your
grandchildren
(or
nieces),
because
these
services
are
typically
outside
the
network
of
your
Internet
provider
(think
sending
a
package
on
the
other
side
of
the
world:
you
ship
it
at
the
local
post
office
but
the
Postal
Service
will
choose
someone
else
to
deliver
it
outside
of
the
country.
How
good
is
this
someone?
And
what
delivery
speed
class
has
been
asked
by
the
Postal
Service?)
With
this
Fingbox
test
you’ll
find
out
if
your
Internet
provider
is
selling
you
a
100
Mbit/s
“last
mile”
connection,
but
takes
you
to
the
Internet
backbone
with
less
(very,
very
common,
especially
during
prime
time,
because
to
be
economically
viable,
the
service
provider
applies
some
degree
of
“overbooking”
to
the
expensive
Big
Internet
connection).
