And did you point out to the ISP that the 80% loss _is not_ normal? Here
is today's mtr from California back to that machine:

As you can see, it's pretty clean right now with only 5% loss. However,
all of the above is subject to change if the path nodes get a burst and
start dropping packets due to high volume. That part is normal - 99.2%
loss is not (http://dotancohen.com/images/examples/bezeq.html). You

Looks like others have been having similar problems.
