DE-CIX explores orbital interconnection with Space-IX

Internet exchange (IX) operator DE-CIX is extending its interconnection vision beyond Earth through its Space-IX initiative, which aims to connect satellite constellations and space-based assets with terrestrial digital ecosystems. The company, which operates more than 60 internet exchanges worldwide and connects over 4,000 networks, is investigating what the first orbital IX could look like. Ivo Ivanov, CEO of DE-CIX, says, "Wherever networks are created, interconnection should follow. "We’ve spent 30 years building the backbone of the internet here on Earth. Now, we’re bringing that same neutral, high-performance interconnection model to the next layer of digital infrastructure, above the clouds and to the stars." Research into satellite connectivity DE-CIX is working with the German Aerospace Centre (DLR) on the European Space Agency’s OFELIAS project, which is researching how laser-based communications can improve satellite connectivity. Optical links promise higher data rates than radio-based systems, but require advanced protocols to mitigate challenges such as atmospheric interference and cloud cover. While OFELIAS focuses on data flow between satellites and ground stations, DE-CIX’s broader Space-IX initiative is investigating how to interconnect space-based infrastructure at scale, laying the foundations for an orbital internet exchange. Bridging space and terrestrial ecosystems "As satellites become part of the digital supply chain - whether delivering broadband to underserved communities, powering AI for businesses, or enabling orbital analytics - we need an architecture that unites space and Earth into one seamless ecosystem," Ivo continues. "This collaboration is the very beginning of our answer to that challenge." In August, DE-CIX India became the first Internet Exchange in the country to integrate Starlink into its ecosystem. Through Space-IX, DE-CIX is working with satellite operators to ensure orbital networks connect effectively with terrestrial infrastructure, particularly for latency-sensitive applications. From global broadband and IoT to remote sensing and AI, the space economy is projected to reach $1.8 trillion (£1.3 trillion) by 2035. DE-CIX argues that orbital networks must interconnect intelligently with terrestrial networks, content providers, and cloud platforms to avoid developing in isolation.

Quantum-ready FN-DSA (FIPS 206) nears draft approval

NIST has submitted the draft standard for FN-DSA (FIPS 206), the FALCON-based digital signature scheme, moving it closer to formal adoption as part of the post-quantum cryptography (PQC) standardisation process. FN-DSA was selected alongside ML-DSA and SLH-DSA for PQC standardisation, but its approval has taken longer due to mathematical complexity and refinements to its components. With the draft now submitted, the first release is imminent. The draft will be published as an Initial Public Draft (IPD) for open review. While the timeline has not been finalised, it may coincide with the NIST PQC Standardisation Conference in September 2025. Based on past schedules, the review period is expected to last around one year, with a final standard likely in late 2026 or early 2027. Industry preparations Companies such as DigiCert, a US-based digital security company, are preparing for FN-DSA’s rollout. To avoid confusion around naming and identifiers, DigiCert has stated it will not implement FN-DSA in production until the standard is finalised. In the meantime, the company will make the IPD version available for experimentation through DigiCert Labs, which already hosts FALCON for testing. This will enable the wider community to trial the draft standard before formal approval. Role in post-quantum cryptography FN-DSA is seen as a special purpose scheme rather than a replacement for ML-DSA. Its smaller signature sizes could reduce certificate chain lengths, which is valuable in environments where efficiency is a priority. However, due to the complexity of FALCON’s signing process, FN-DSA is less suited for frequently signed leaf certificates. Instead, it is expected to be more useful for root and intermediate certificates. NIST has also signalled potential adjustments to signing and sampling methods, which could broaden FN-DSA’s applications once the draft specification is published. The progress of FN-DSA marks another milestone in the move towards quantum-safe standards. Organisations are being encouraged to begin preparation now by testing draft algorithms, trialling implementations, and developing crypto-agility strategies to ensure a smooth transition as PQC standards are finalised.

Pelagos planning ambitious 250MW facility in Gibraltar

Pelagos Data Centres, a developer of large-scale data centre infrastructure, has announced plans to build a major new data centre near the Port of Gibraltar, with capacity of up to 250MW by 2033. Unveiled at a launch event at the offices of Gibraltar’s Chief Minister, Fabian Picardo, the project represents an investment of around £1.8 billion. It is the largest development currently planned in the territory by value, and among the largest in its history. The facility will be built in five phases on a 20,000m² site. The first stage is scheduled to be operational in late 2027, with later phases delivered at intervals of around 18 months. Transforming Gibraltar’s digital landscape Funded entirely by private investment and backed by the Government of Gibraltar, the project is positioned as a step forward for the territory’s digital and economic development. It is intended to help meet Europe’s growing demand for data centre capacity, particularly as AI adoption accelerates across industries. The site will operate independently of Gibraltar’s existing power grid and include a public leisure facility as part of the development. Konstantin Sokolov, Chairman of Pelagos Data Centres, comments, "The scale of this project marks a new chapter for Gibraltar and for Europe's digital capabilities. "Just as electricity and the internet transformed society in the past, AI is now emerging as the defining technology of our time with the power to redefine entire industries, economies, and communities. "With our new facility, Pelagos Data Centres is laying the foundation for the next era of AI-driven innovation, positioning Gibraltar as a strategic hub and enabling Europe's brightest minds to unlock the full potential of this revolutionary technology." Chief Minister Fabian Picardo adds, "I am delighted that Pelagos Data Centres have decided that Gibraltar is the place to establish their first facility and that the whole community will benefit from their massive investment and its huge economic impact. "I look forward to this project becoming a reality as soon as possible." Jobs, efficiency, and sustainability The development is expected to create up to 500 jobs during construction and around 100 permanent positions once operational. Pelagos currently employs 50 full-time staff across London and Gibraltar, and plans to expand its local workforce significantly. The facility will be built to Tier III standards, carrier-neutral, and designed to serve both public and private sector clients. It will pursue international certifications covering information security, quality, sustainability, and energy management, with a targeted Power Usage Effectiveness (PUE) of 1.2 or better. The project’s sustainability strategy includes powering operations with a combination of renewable energy and liquefied natural gas (LNG), with the aim of achieving net-zero operational emissions by 2030. Cooling systems will be designed to minimise water use, and the company is exploring heat recovery options to support community projects. Sir Joe Bossano, Minister for Economic Development and Inward Investment, says, "This is the most significant infrastructure investment in Gibraltar since the early 1990s, when the GSLP Government brought state-of-the-art telecommunications as inward investment from the United States and made possible the creation of a centre for online services. Then, we future-proofed Gibraltar's economy. Today, we are doing so again. "The technology of the future - on which every advanced economy will depend - will be artificial intelligence. AI requires data, processing power, and energy resources on a scale never before seen. "The Ministry for Economic Development will put all its resources at the service of this initiative to ensure that it is delivered in the shortest possible time. In this field, speed of delivery is everything. Gibraltar should be the fastest jurisdiction on the planet when it comes to delivery." A further technical briefing and press conference is planned for the first quarter of 2026, ahead of construction beginning later that year.

Castrol and Airsys partner on liquid cooling

Castrol, a British multinational lubricants company owned by BP, and Airsys, a provider of data centre cooling systems, have formed a partnership to advance liquid cooling technologies for data centres, aiming to meet the growing demands of next-generation computing and AI applications. The collaboration will see the companies integrate their technologies, co-develop new products, and promote greater industry awareness of liquid cooling. A recent milestone includes Castrol’s Immersion Cooling Fluid DC 20 being certified as fully compatible with Airsys’ LiquidRack systems. Addressing rising cooling demands in the AI era The partnership comes as traditional air-cooling methods struggle to keep pace with increasing power densities. Research from McKinsey indicates that average rack power density has more than doubled in two years to 17kW. Large Language Models (LLMs) such as ChatGPT can consume over 80kW per rack, while Nvidia’s latest chips may require up to 120kW per rack. Castrol’s own research found that 74% of data centre professionals believe liquid cooling is now the only viable option to handle these requirements. Without effective cooling, systems face risks of overheating, failure, and equipment damage. Industry expertise and collaboration By combining Castrol’s 125 years of expertise in fluid formulation with Airsys’ 30 years of cooling system development, the companies aim to accelerate the adoption of liquid cooling. Airsys has also developed spray cooling technology designed to address the thermal bottleneck of AI whilst reducing reliance on mechanical cooling. "Liquid cooling is no longer just an emerging trend; it’s a strategic priority for the future of thermal management," says Matthew Thompson, Managing Director at Airsys United Kingdom. "At Airsys, we’ve built a legacy in air cooling over decades, supporting critical infrastructure with reliable, high-performance systems. This foundation has enabled us to evolve and lead in liquid cooling innovation. "Our collaboration with Castrol combines our engineering depth with their expertise in advanced thermal fluids, enabling us to deliver next-generation solutions that meet the demands of high-density, high-efficiency environments." Peter Huang, Global President, Data Centre and Thermal Management at Castrol, adds, "Castrol has been working closely with Airsys for two years, and we’re excited to continue working together as we look to accelerate the adoption of liquid cooling technology and to help the industry support the AI boom. "We have been co-engineering solutions with OEMs for decades, and the partnership with Airsys is another example of how Castrol leans into technical problems and supports its customers and partners in delivering optimal outcomes."
