Hi Rainling,

Thanks for reaching out!

It's a bit tough to speculate on what may be going on here with the limited amount of data we can see in the screenshot you provided. There's definitely some packet loss occurring at the final destination in your trace - and it *appears* that it's starting at hop #2, but we can't tell for certain without being able to see some additional information for the intermediate hops.

If you're interested, we've got a great walkthrough guide that goes over how to use PingPlotter to troubleshoot network issues like this one, which may prove helpful to you here as well:

We also just launched a new pilot program called PingPlotter Reader, if you'd like us to help out with your troubleshooting efforts. With this service, we'd actually remotely monitor your connections for you over a period of time, and then compile our findings into a report. If you're interested, you can find more details on PingPlotter Reader here:

Hopefully this helps out! If you have any other questions - please let us know.

Best wishes,

-Gary
