It occasionally tries the high-latency servers, because it decays the low-latency SRTT. The purpose of this is to prevent permanently blackholing a server when it's temporarily slow. So every now and then it will switch to the high-latency server. If it's still high latency, it will lose preference again, and it will go back to the low-latency servers. But if it has gotten better, it will continue to be used. Network distance is not the only reason for high latency, sometimes it can be because of heavy load on the server, or a congested network link, or other temporary conditions. -- Barry Margolin Arlington, MA _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
