Keeping Sweden in sync with Netnod’s Time and Frequency services

Netnod’s time and frequency services

Netnod provides the Swedish distributed time service using Network Time Protocol (NTP) and Precision Time Protocol (PTP) to provide a robust, reliable and highly accurate source for time and frequency. As one of the leading players in the development of Network Time Security (NTS), Netnod provides the most secure time services available.

Netnod’s PTP service is delivered over a dedicated fibre and offers a robust, reliable and highly accurate source for time and frequency. If you are working in a sector where every nanosecond counts, you can trust Netnod to keep you on time.
Keeping Sweden in sync - NTP is the most commonly used protocol for synchronizing the time on computer systems. An accurate, NTP-based system is essential not only for individual users but also for local and national economies.
Time and Frequency
Netnod’s Network Time Security (NTS) service is one of the first NTS-enabled time services in the world. This page gives a brief introduction to NTS, its benefits, and how to set it up on your devices.
These are the technical details for Netnod’s NTP service and how to reach our Internet Time servers.
What is White Rabbit and why does it matter for high accuracy time services?

Initially developed by CERN, White Rabbit is at the cutting edge of high accuracy time systems. To find out more about how it works and why such high accuracy is important, I talked with Ragge Sundblad, who has been working on the preliminary study of White Rabbit at Netnod.

Providing traceable time to the highest levels of accuracy is essential for industries ranging from telecommunications and the energy sector to financial and trading services. Precision Time Protocol (PTP) services provide traceable time over a dedicated fibre which enables organisations to time stamp to the highest degree of accuracy. 

Stockholm, 7 July 2021 - Netnod, a leading provider of interconnection, DNS and time services, today announced a new time and frequency site in Luleå, Sweden. The new site brings a highly accurate, local source of Swedish time to Luleå enabling anyone to get this time for free via the Network Time Protocol (NTP).

A lot of the Internet’s most important security tools are dependent on accurate time. But until recently there was no way to ensure that the time you were getting came from a trusted source. The new Network Time Security (NTS) standard has been designed to fix that. In this post, we will summarise the most important NTS developments and link to a range of recent Netnod articles providing more information on the background, the NTS standard and the latest implementations.
