Netometer ping data are collected every 15 minutes, every day of the year. Ten sites are pinged 10 times each, and grand mean minimum, mean mean, and mean max ping times are archived. This chart shows mean minimum, mean mean, or mean max ping time frequencies with 11 categories evenly dividing the variable range.

FYI: Regression on these (log-log) data points gives a line with slope of -0.43 and y-intercept of 2.50. The correlation coefficient is -0.295134544081585.
