Abstract:

© 2018 IEEE. We collect high resolution timing packet data from 459 public Stratum-1 NTP servers during the leap second event of Dec. 2016, including all those participating in the NTP Pool Project, using a testbed with GPS and atomic clock synchronized DAG cards. We report in detail on a wide variety of anomalous behaviors found both at the NTP protocol level, and in the detailed timestamp performance of the server clocks themselves, which can last days or even weeks after the event. Overall, only 37.3% of servers had Adequate performance overall.
