What trends and challenges have you been noticing in Europe’s connectivity landscape, and how is Telxius staying ahead? 

We’re seeing a real shift in Europe’s connectivity landscape, especially with the growth of AI, cloud computing and real-time applications. AI is a major opportunity, while also posing the challenge of adapting to hyperscale requirements, and strongly impacting data centre demand, the evolution of connectivity and data volumes.

On top of this, more locations are emerging as key European data hubs beyond the traditional FLAP markets of Frankfurt, London, Amsterdam and Paris. There’s rising demand in edge and secondary markets like Madrid, Milan, Marseille and the Nordic countries, as businesses look to bring services closer to end users and diversify network paths.

To stay ahead, Telxius has significantly expanded its terrestrial footprint with high-capacity, carrier-neutral infrastructure like our Derio data centre in Bilbao in northern Spain – linking Europe’s major connectivity hubs, while supporting growing edge locations. We also have strong interconnectivity rings in both northern and southern Europe.

Carriers, content providers, ISPs and hyperscalers are demanding that data moves more efficiently and securely, as well as closer to the edge. With this in mind, we are now diversifying our product portfolio with new solutions like Connect to Cloud and ContentConneX, alongside CDN and landing services.

We are also serving new customer segments including the satellite sector with tailored offerings like Gateway Land Lease. We continually develop our solutions portfolio to address the changing needs of our customers and the market.

Have there been any recent updates to the company’s subsea business?

Yes, there’s been significant progress. Although the transatlantic route remains one of the most competitive, we’re continuing to grow our presence with high-performance backhaul routes reaching European hubs. We’re also providing key landing facilities to some new systems developed by hyperscalers.

Furthermore, on the other side of the Atlantic we announced plans for a new subsea cable, CELIA, connecting key hubs in the Caribbean and US. This will complete the replacement of our original SAm-1 cable and enhance the Telxius next-generation subsea ring around Latin America.

We’re also very excited about Firmina, which is already in service and connects the US east coast, Santos in Brazil and Las Toninas in Argentina.

How is your infrastructure strategy evolving to meet growing needs for resilience, scalability and low latency?

Our strategy has always been focused on building a network ready to meet the demands of tomorrow. That means optimising how we connect subsea cables to terrestrial backhaul routes and key data centre locations with minimal latency and maximum reliability.

We also pay close attention to how quickly the market shifts. Efficiency is a huge priority, and we always put measures in place that enable us to scale up quickly and invest in areas where we see opportunity.

At the same time, we’re always exploring new technologies and partnerships to strengthen our offerings. For example, we recently completed an industry first with Ciena, comprising a 1.3Tbps single wavelength transmission across our Marea submarine cable between Virginia Beach in the US and Bilbao in Spain. We’re committed to continually upgrading the Telxius network with enhanced technologies to better support customers. 

What are some of the driving factors in the strategy that Telxius follows for network expansion?

We are evolving with a strategic vision to connect the world’s largest data centre hubs. For instance, thanks to Firmina, we’re landing in Myrtle Beach, enabling us to deliver the lowest latency to the rapidly growing data centre location of Atlanta.

We’re also putting a larger focus on our colocation capabilities globally, often at strategic coastal locations to leverage our subsea cables, reduce latency and maximise performance. We currently operate 26 landing stations and data centres worldwide, all directly connected to our 100,000km subsea and terrestrial network.

We are continually evolving and expanding our network each year. In fact, it has more than tripled in size over the past few years, providing a differentiated ecosystem with strong competitive advantages.
