Remember (and maybe someone can link to the trace route interpretation PDF from Nanog) that if the packet loss doesn't continue end to end then its not likely a real issue as the forwarding plane isn't loosing packets. The loss on a single hop either points to limits on ICMP responses on the control plane, or congestion on the forwarding plane. On Feb 28, 2014 5:09 PM, "jay lark" <jay@jaylark.com> wrote:
We've also see increased packet loss and latency over the past week or so from our London Level3 office to our Verizon offices in NY and LA. Routes to our ATT office in Chicago have been okay for the most part.
Here's a current trace from London to LAX. Heavy packet loss in London. It was in Paris before that J

We've been having issues in San Jose the past two days on both L3 MPLS and Internet circuits. MPLS was resolved yesterday with these notes:
"Event The IP NOC advised that troubleshooting is ongoing with the equipment vendor to further isolate the point of failure. Additionally, it has been advised that voice services are impacted and calls are failing network wide. Collaborative troubleshooting efforts between the IP and Voice NOC and the equipment vendor will continue in an effort to expedite service restoral."
However, we're still having internet issues.

That's what we told our customer... by the time they replied, the issue had gone away.

As always, trace routes are helpful. We've been having intermittent issue with Level 3 routes for the past couple weeks, most issue for us seem to be when going from Level 3 to Global Crossing routes.

We had a report from a customer earlier this morning, but they advised the problem went away.
We connect to Level3 at Southfield MI.

Anyone seeing Level3 routing issues? We just observed a massive drop in
routes in the BGP feeds and seeing some strange ICMP issues along their
backbone in terms of traceroutes along their backbone. They might be
adding some filters based on the recent DDOS attacks, I can ping
interfaces but traceroutes go to hell...
