Re: Abnormal Pings With Roadrunner

If you drive your car to Poughkeepsie or Kankakee, you are near every location in those cities. The internet doesn't work that way.

Routing is everything. Destination is nothing. In most cities there is very little interconnection between local sites.

If you run trace routes, run them to the sites of interest to you. Comparisons make no sense otherwise.

The reason for comparisons is to find the common path and common choke points. You can trace to the same destination from different start points, often there's a common destination path that may show similar issues. You can trace to different destinations from the same start point and check to see if and where in the common path an issue appears.

The goal is to find the problem by running data multiple ways to eliminate as many single data points as you can. Another PC with the same issue, usually eliminates the PC. Another neighbor with the same issue, usually eliminates the home wiring. Another area with the same issue, usually eliminates the local last mile network. Another ISP with same issue, usually eliminates the ISP. etc, etc.
