Huh? I'm confused. What does your test zone have to do with pool.ntp.org ? On pool.ntp.org each DNS server is currently giving out the same set of up to about 14 servers on each request. The zones are often not quite in sync between the servers. Also, the zone data changes more often than the servers update and again the servers update more often than the TTL for clients is -- this is to try to spread out different data on the different end-user DNS caches. However in the case of Turk Telekom it probably just makes it worse because they'll cache one set of 14 IPs and give that to all their equipment for 45 minutes (or whatever the TTL is). - ask -- http://develooper.com/ - http://askask.com/ _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
