Sudden traceroute time jump between ISP and requested server

1

I've been having trouble these past few months with certain websites timing out or acting really slow, so I decided to do some traceroute testing. One particular website I try to access called "vp.crossmark.com" is very bad about its loading time. Following is the tracert output for the URL above:

C:\Users\[USERNAME]>tracert vp.crossmark.com

Tracing route to vp.crossmark.com [64.128.22.182]

Here's another for comparision:

C:\Users\[USERNAME]> tracert vp.crossmark.com

I noticed that the ping time between the suddenlink servers and the servers that connect to crossmark takes a massive jump into the 200-400 range. I've repeated this a few times and I constantly find massive jumps in ping time or even several timeouts at the same point between networks.

I'm wondering if this is a sign of connectivity issues between my ISP and the servers I am requesting. This website isn't the only one doing this by the way, but most larger sites like google, youtube, or wikipedia make the jump without sudden ping time increase.

Just tried a tracert, didn't do it for me, also came with a diff URL but the same ip – Kilisi – 2015-10-20T23:24:30.667

It's clearly and obviously not since the times to points past that are just fine. If this were a problem with a slow router or link, all points past it would show a delay as traffic passes through that slow point. All you have here is a router that's not a very good responder.

This isn't unusual, by the way. Modern Internet core routers are heavily optimized to be efficient forwarders, the most efficient we can possibly make them. Sending ICMP responses takes a much slower path that typically requires passing through a CPU that gives a much higher priority to other tasks like updating the forwarding table. – David Schwartz – 2015-10-20T23:24:32.303
