Adrian correctly guessed half of the solution: 1) The NTP Pool server was sharing a 10Mbit connection before with perl.org. Occasionally that'd get busy enough to create a bit of latency/jitter. Over the last couple of weeks the pool servers and perl.org each have a 100Mbit link (thanks to http://www.phyber.com/ ) 2) The check script is really a simple SNTP client -- it checks the time against a "known good" server. Before that was just one of my ntpd's on a regular Linux or FreeBSD box (I forget which) -- now it's an ntpd on an awesome Meinberg lantime server with a GPS antenna on the roof. (Which obviously gives a much better "baseline" to check against). - ask _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
