Running VMS 5.4-1 on both platforms with Multinet 2.2F (which contains NTP), a VAXstation 3100 (called Lane) and a VAX 9000-210 (called Kuhub) had been up for more than 8 days, and more than 1 day, respectively. As we made some hardware changes on our Internet router Internet became unreachable for about 105 minutes. Both Lane and Kuhub used exactly the same stratum 1 servers. At the end of the 105 minutes of isolation the time difference between Lane and Kuhub was approximately 2 seconds. That's approximately a relative drift of 1 part in 3000. Why am I seeing such a large drift?
