clarification: Re: links on the blink (fwd)

btw, That's 10^-5 packet loss (0.001%).  I just got email asking what
the units were.  I think the acceptance test uses 1000 byte packets.

Steve,

Enough of your wild stories of -0%- loss.  :-)  The correct figure was
10^-5 for acceptance with 10^-4 being the maximum threshold we would
accept on a running circuit before contacting MCI to take the circuit
in a maintenance window for diagnostics.  That doesn't mean we
wouldn't bug MCI to get the circuits back perfectly clean.  ;-)

We still have the same criteria.  I think MCInet is also as vigilant.
