Anyone from Verizon/TATA on here? Possible Packet Loss

Hi guys,

We host a web application for a client and they've been complaining that it's been slow since yesterday. It seems fast from the locations I've tested and the system looks fine, so I suspected there was packet loss going on somewhere between them and our colo facility. 

I did a few trace routes from our firewall to the client's IP and most of the time they look fine, however I occasionally see some packet loss.

Good trace route:

 1  65.61.0.97 0 msec 0 msec 0 msec
 2  107.1.118.217 0 msec 10 msec 0 msec
 3  69.139.194.21 0 msec 0 msec 0 msec
 4  68.86.147.129 10 msec 10 msec 20 msec
 5  68.86.94.169 20 msec 30 msec 20 msec
 6  68.86.86.26 20 msec 20 msec 10 msec
 7  216.6.87.97 10 msec 20 msec 20 msec
 8  216.6.87.34 10 msec 20 msec 10 msec
 9  152.63.34.22 20 msec 10 msec 20 msec
 10 130.81.28.255 30 msec 30 msec 20 msec

Traceroutes with packet loss (8th hop):

 1  65.61.0.97 0 msec 0 msec 0 msec
 2  107.1.118.217 0 msec 10 msec 0 msec
 3  69.139.194.21 0 msec 0 msec 0 msec
 4  68.86.147.129 20 msec 10 msec 10 msec
 5  68.86.94.169 20 msec 20 msec 30 msec
 6  68.86.86.26 20 msec 20 msec 10 msec
 7  216.6.87.97 10 msec 20 msec 30 msec
 8  216.6.87.34 10 msec *  10 msec
 9  152.63.34.22 140 msec 110 msec 20 msec
 10 130.81.28.255 20 msec 30 msec 30 msec

 1  65.61.0.97 10 msec 0 msec 0 msec
 2  107.1.118.217 0 msec 10 msec 0 msec
 3  69.139.194.21 0 msec 0 msec 0 msec
 4  68.86.147.129 20 msec 20 msec 10 msec
 5  68.86.94.169 30 msec 20 msec 20 msec
 6  68.86.86.26 20 msec 20 msec 20 msec
 7  216.6.87.97 20 msec 10 msec 20 msec
 8  216.6.87.34 20 msec 40 msec * 
 9  152.63.34.22 20 msec 10 msec 10 msec
 10 130.81.28.255 30 msec 30 msec 20 msec

It appears the 8th hop occasionally has packet loss. 

Thanks,
Derek
