Network Time Protocol quietly 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 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 for 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, rather than replacing it.
Within Time-as-a-Service, organisations can choose the approach that best aligns with their operational and regulatory requirements.
Public NTP remains a trusted and widely used solution for time synchronisation across the internet. As part of AMS-IX Time-as-a-Service (TaaS), it provides a reliable and accessible way to keep systems aligned.
For organisations exploring additional levels of control and resilience, Private NTP offers a complementary approach with a dedicated, satellite-independent time source.
