Internet services in Antarctica

Hi, I have a hobby project running DNS service to people looking for NTP public servers. I noticed that the DNS servers apparently get ~5 thousand queries per day from IPs that the GeoIP database we use claim are in in Antarctica. It’s less than 0.0001% of the overall DNS queries, but it made

Re: Recent NTP pool traffic increase (update)

Hello, Those servers aren’t (and have never been) part of the NTP Pool - https://www.ntppool.org/en/ If they were you could remove them from the system and over the next hours, days and months the traffic would go away. We also have features to change the relative amount of clients you get
