Re: High latency from 8-11 PM every night in Raleigh, NC

Tracert is misused daily here.

You need to worry about the destination ping. If your destination is 150ms, most likely there is a problem and going bottom to top you would likely see a 130ms to 30ms bump for example.

Please post tracerts during those hours, as the ones posted don't have a issue.

If you destination is 50ms, any router reporting 50+ is just from that ICMP packet being put on the back burner while the router deals with real traffic. Disregard any ping above the destination ping!!!

Thanks for the replies, guys!

I setup PingPlotter to show pings for hop 4 (the first hop that shows lag) and hop 13 (the final hop at Google). Here is a snapshot of the data taken during the middle of last night's lag window: »i.imgur.com/VTdc8oY.png

Also, here are my signals: »i.imgur.com/285VYIj.png (though I just took this, outside of my lag window -- I can post them again during tonight's lag, if you suspect they'd be any different)

And the reason why I wasn't displaying the destination ping before, was that TWC has said in the past that they can't control anything beyond their routers, so I wanted to just highlight the fact that it appears to be happening on their hops. But good to know.
