It does however, seem to have had the unfortunate side effect of knocking a number of servers out of the pool, dropping it down to either remaining.
The Oceania pool is down to 48 from 67 IPv4 servers in the last 7 days. http://www.pool.ntp.org/zone/oceania 19 servers removed in a week, not quite 30% of servers, whether that was 30% of the pool serving capacity or not is a different story. Some stats from a 10 minute dump from one of my machines in the AU/Oceania pool with "net speed" 50Mbps shows: 5,537,572 queries 1,345,772 unique IPs The top 50 /24s accounted for 6% of the queries. The top 50 /24s were from T-Mobile, Sprint, Telstra in that order. The top 50 individual IP sources accounted for 21k queries. More than 1000 IPs sent over 100 queries in the 10min window. Quite surprising to see so many queries from outside of our region, I wonder if the DNS geolocating for the NTP pool isn't quite working as it should. Then again I haven't looked that closely recently. Cheers, Joseph
