And how exactly would you interpret the number returned by net_loss
(int), in a column called "LOSS", in reference to reachability of a
"hop" between two end points:


The hop not sending out the ICMP message for those packets, either
because its CPU is overloaded or because of a configuration option to
rate-limit them.

Thank you. The former seems close to what may have happened, with a possible impact beyond ICMP, as once having moved my client over to their Broadwing connection, their processing from Yahoo's site seems to have come back to where it was a few days ago.

Thanks again,
