RE: Lima, OH Spectrum/Charter Severe Node/Hop Latency Issues

Austin,

 

If you run MTRs or traceroutes through the node, is there any other
additional packet loss seen in the path, and at the destination? What does
the reverse MTR or traceroute look like? The attached image was stripped out
by the mailing list system.

 

Bufferbloat is controlled at the firewall level, which is different from
packet loss and disconnects.

Hello all, 

 

One of my NetOps engineers resides in Lima, Ohio and they are receiving
terrible bufferbloat, packet loss, and random disconnects.

 

I have been pinging 24.33.160.213 (Lima, OH Spectrum/Chart Node) and it's
rejecting a ton of packets. This has been going on for weeks.

 

Node having problems: lag-1.limaohid01h.netops.charter.com

 

NOC seems like they don't care, same with OSP in the field.

 

There is no reason why this hop (#13) should have up to 613ms ping times. 

 

Thank you,

Austin
