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.=20
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 20 msec 10 msec 20 msec
8 216.6.87.34 20 msec 40 msec *=20
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.=20
Thanks,
