level3.net in Chicago - high packet loss?!?

In message <38D1AE7F-52FA-4BCF-A32F-CF40FA958DC6@gmail.com>, Network Fortius wr

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,

Oh, yes. Is it just me, or did this read as: "Bah! But I was
right anyway, all you suckers!"

?

Go on, amuse the crowd.

I am sorry, if you interpret it this way. I do not have much choice, when it comes to servicing people asking for immediate resolution, so it is either trying to determine (via the wrong tool, in this case?!?) if there is something going on, during Labor Day, when the client still accepts "toying around", or the knee-jerk reaction to move them first thing Tuesday morning, then trying to philosophize around the problem. Again - please accept my apologies - it must have been just a coincidence that my lack of properly interpreting the tool output, combined with something actually having happened on the client's side, led to the wrong assumption that things were wrong in a place that the tool's output should not have been indicative of.

Apparently it’s just you.

Nice job on taking an on-topic discussion and then flaming the original poster who (based on my personal subjective read of the responses) was geninuinely asking for assistance and appears to have gleaned some value from this thread and got her client’s service restored. Consider the value of your post prior to doing it.

For those asking me to do the same, the value is to bring more attention to the lack of moderated influence on nanog. While recognizing it is nobody’s full-time job to baby-sit this forum, I find that posts from the steering committee are generall heeded. Further, attacking those looking for help in no way aides the network community as a whole and you present yourself as elitist. People may be misguided and may be off topic, but helping them get where they are trying to go is our job in many levels.

My apologies for providing troll food.
