RIPE Atlas K-root IPv4 statistics for 2014-09-26
================================================

The 2.5 percentile ("best case"), 50 percentile (median) and, 97.5 percentile ("worst case") of the probe's RTT distribution were computed for each probe making the measurement.

The “median median" refers to the median of all the median RTTs from all individual probes
in a region. For example, a “median median" of 30ms means half of the probes in the region reported a median RTT of at most 30ms.
