I am trying to understand what some of the data in Ping Plotter means. I have posted a screenshot of the graphs I get for a problem I'm trying to troubleshoot. Comcast should be out here today to address the problem evident in the first and second graphs, but what is causing the curious repetitive pattern on the 5th and 6th graphs?

Also, what is happening in the bottom (7th) graph? How would I go about resolving this problem (if it is one), since it's not my own (or my game site's) ISP, but somewhere in between?

The graphs display a 12 hour period of 15-second interval traceroutes.

Thank you in advance for your help.

Susan
