I may be having a problem with my RoadRunner service dropping packets. The cable company brought their high-priced analyzers here to do flood testing, and they could not find an issue.

What's strange is that when I start a ping test with pingplotter, the result line is a few bumps indicating low or no packet loss. However, if I close the graphic window and open it again, the picture below shows up. Is that problem a bug in PP?

The bottom line is I need to know how to read these results. My Internet connection is nowhere near as bad as this graph looks.
