Network Time Protocol underpins the synchronisation of the digital world. Within AMS-IX Time-as-a-Service (TaaS), organisations can choose between Public NTP and Private NTP, each serving a clear and distinct purpose.
Public NTP is widely used, free, and accessible via the internet. It is supported by universities and internet infrastructure organisations, including AMS-IX. For most organisations, it provides reliable and sufficient time synchronisation for everyday operations.
Public NTP ultimately traces back to satellite-based systems such as GPS. These signals are highly accurate, but they originate from space and arrive on Earth relatively weak. This creates a dependency that is important to understand, particularly in more critical environments.
Delivered within AMS-IX connected data centres, it provides a dedicated and secure time signal sourced directly from VSL via fibre. This ensures accuracy, traceability, and independence from satellite systems.
This makes Private NTP particularly relevant for:
Public NTP remains an essential part of the internet. Private NTP complements it by offering an additional layer of resilience and control.
Within Time-as-a-Service, organisations can choose the approach that best aligns with their operational and regulatory requirements.
Private NTP is designed for organisations where accuracy, traceability, and resilience are critical. As part of AMS-IX Time-as-a-Service (TaaS), it offers a secure and satellite- independent approach to time synchronisation.
For many organisations, Public NTP continues to provide a reliable and widely adopted solution for everyday use.
