Webinar recording: the importance of timing resilience in data centres
As data centres continue to evolve into a cornerstone of national digital infrastructure, the importance of robust and resilient timing systems is gaining unprecedented attention. techUK hosted the National Physical Laboratory and industry experts for a discussion to highlight how timing is no longer a niche technical requirement but an essential component underpinning the reliability, security, and performance of modern digital services. With increasing interdependence between data centres and telecommunications networks, timing resilience is emerging as a strategic priority for operators, customers, and policymakers alike.
Why timing matters more than ever?
Data centres now play a central role in supporting economic growth, national security, and the functioning of critical sectors. Recent industry analyses show that the data centre sector contributes significantly to national GDP, supports thousands of jobs, and is essential to government ambitions around sovereign compute capacity. The rise of AI and ever growing demand of compute power across all sectors only amplifies the need for precise, reliable timing.
The panel showcased why timing resilience should be seen as essential as power or cooling. Data centre operators must ensure synchronisation not only for their internal systems but also for customers, particularly in multi tenant environments where industries such as finance, healthcare, and AI bring diverse and stringent requirements.
Historically, many customers have relied on satellitebased timing for precision. But those systems come with vulnerabilities - ranging from signal interference to spoofing - that can pose significant operational risks. As awareness of these vulnerabilities grows, the sector is beginning to recognise the need for alternative, terrestrial sources of trusted time and for a more holistic approach to timing resilience.
Technical drivers and evolving requirements
Synchronisation needs are no longer confined to specialist applications. Today, distributed computation, highfrequency telemetry, and reduced latency architectures all depend on stable and accurate timing.
Operators serve dual roles: they need precise timing for their own infrastructure, and they increasingly provide timing signals as part of their services to customers. However, measuring timing performance at the application level remains challenging - especially in highly sensitive sectors such as finance, where even microsecond discrepancies can have major implications.
Emerging protocols and test methodologies aim to close this gap, but broad adoption is still in progress. Regulatory drivers are also accelerating interest in resilient timing. Frameworks such as operational resilience regulations and international audit standards now influence customer expectations, prompting more organisations to request verifiable evidence of timing integrity and robustness from their data centre providers.
Work is underway across international standardisation bodies to develop interoperable timing solutions, define performance thresholds, and enable multivendor ecosystems. Many governments are now taking a “system of systems” approach that blends terrestrial and satellite-based timing as part of wider positioning, navigation, and timing (PNT) resilience programmes. This integrated approach aims to reduce reliance on any single technology and promote the development of locally resilient solutions.
Building awareness and strengthening the community
Despite the increasing importance of timing to data centre operations, awareness remains uneven. It is important that customers are conscious of the consequences of the vulnerabilities inherent in current timing practices, particularly where reliance on satellite signals persists. The sector needs collective education, shared best practice, and community advocacy to ensure that timing resilience becomes standard rather than optional.
Timing resilience will continue to grow as a strategic priority as data centres become ever more critical to national and global infrastructure. With increasing emphasis on redundancy, innovation, and regulatory alignment, the sector is wellpositioned to lead in developing resilient timing solutions that support the next generation of digital services.
