• As expected, the network was perfectly healthy but what caught me off guard was this message: I was not expecting ping to take countermeasures that early on in a day.

• In this case ping resets the latency measurement to zero.
• "taking countermeasures" is nothing more than just marking an erroneous measurement as if it was 0ms.
