Intermittent high ping times ( 1000 Ms - 9000 ms ) to head end first hop

Has anyone had a resolution to theintermittant high ping tomes to the first hop on the verizon network? Since May I have been losing connecton to the internet as wvery hop starts having multi second ping times. Oddly the packets aren't getting dropped, they are just taking 1-8 seconds to return. Ths is maddening and constant and Verizon Fios support and the mysterious network team keep coming out and replacing random things.

Comcast is looking great about now.

When my problem occurs I get traceroutes like these...

A four second ping time to the first hop. If I do a DHCP release and renew on the router the problem goes away for a short time, but it keeps coming back.

Please do not say something like icmp is not prioritized on the network, because one that isn't really tru and two it is completely irrelevant. DNS, web connections, all packets see this issue, and I am more than a little tired of it.

Tech support is coming out again to switch out my cables. I have been a network engineer for 20 years and I am getting stabby with the incompetence displayed here.

Your problem is in your house, look at that ping to your router. That is nasty. It may be masking real network issues too. That ping should be sub 1ms @ all times. Are you hardwired or wireless? Something terrible is going on.  It might seem insignificant, but I have seen that before cause the rest of the trace to be terrible.  

under better conditions if that first internet gateway (VZ) router doesn't get down, then verizon has a job to do and they should do it.

Fix that first and then post a new traceroute

Not sure what you mean.

1 Wireless_Broadband_Router.home (192.168.4.1) 0.444 ms 0.373 ms 1.030 ms  

 

Essentially all about 1 ms or less than half a milisecond, note the decimal. This is from a linux box not windows.

 

The first hop outside my router is a verizon device and it is a 4000 ms hop.

They're using a *nix based machine (Mac/Linux/Unix/BSD) and it's being reported in milliseconds to three decimal places. Their latency is fine to the router 🙂

If no one is saturating the upload on your end it's possible if they've checked and double checked everything including your router, ONT, Coax (or Ethernet) cables, they may wish to start looking for dirty or poor fiber splices nearby and start investigating problems at the OLT and upward into the network. This also includes PON congestion which should not be happening even to that level (due to the way the PON gives time slots to each user on a splitter). Dirty fiber can certainly cause latency issues in addition to OLT issues.
