Maybe caching prevents enough authoritative answers from being returned to cancel out the noise, but I've seen the opposite of what you report. > We operate nameservers in the US and in Europe, and we > definitely see this effect. Maybe it works well over different continents, but simple "use different IPs from different NS" has not given desirable results in my experience. Then we have the failover and TTL issues...
