Median RTT per country and US state

Mapping RTT by political boundaries can reveal where high latency issues are located.

Path Dispersion

The paths taken by different traces show where the majority of a monitor's traffic travels.

Path Length Distributions

Path length distributions show, on aggregate, how well-connected a monitor is to the rest of the Internet.
