Over the last month the NTP Pool has gotten the biggest upgrade it has had in years. The changes has given us much more scalability and performance.
As you might know, the NTP Pool system is essentially a monitoring system and a smart DNS server. Server operators register their server in the system, the monitoring system checks and evaluates the submitted servers and the DNS server gives end-users a (hopefully) local selection of servers, weighted by preferences given by the server operator and other factors.
Last month there was a big change to the DNS server.
