Netnod operates Sweden’s national time service on behalf of the Swedish Post and Telecom Authority (PTS). It is one of the world’s most respected public NTP services and one of the first to deploy NTS (Network Time Security) in production.
The service runs on stratum-1 servers traceable to Swedish official time sources, with anycast entry point ntp.se and dedicated NTS endpoints.
