Random high ping

Solution
You are going to have to do much better testing to get your ISP to fix it.

First your tracert show no actual issues. If you were to give this to your ISP they would correctly claim that even though tracert show some issue with the intermediate hop it has no impact on the final nodes. Since it has no impact on your ability to use the remote server why should they even think to fix it.

The problem is partially how tracert tests. It tests each node in the trace sequentially. If the problem is very intermittent it can test a node and then the problem goes away and the next node is fine and then it starts again and you see delays. Tracert does not go back and check the previous hops.

A actual problem will show delays start in a certain hop and then increase or stay the same in every hop past it.

What you will need to do is try to use standard ping to catch this. What you want to do is open multiple cmd windows and leave constant pings run to. Your router, the first ISP router...normally hop 2 in your trace, and then some common IP like 8.8.8.8

What you need to show your ISP is that your ping to your router shows no issues but the ping to both the ISP router and the final node have problems at the same time.

Since the times to hop2 represent the connection to your house this is the simplest one for the ISP to fix. In some cases though it can be caused by overload of the segment you share with your neighbors and ISP tend to try to deny the problem exists.
