Anyone from Verizon/TATA on here? Possible Packet Loss

After some further troubleshooting, I believe I have narrowed down the issue to one of Verizon's routers (

ping repeat 100
Type escape sequence to abort.
Sending 100, 100-byte ICMP Echos to, timeout is 2 seconds:
Success rate is 91 percent (91/100), round-trip min/avg/max = 20/26/30 ms

I had my client send me the output of the ping command (100 pings) and a trace route. 

Their 5th hop is and one of the response times in their trace route was 175ms so the issue seems to be around there.

I asked them to open a ticket with Verizon to take a look.
