How Zayo is Expanding Fibre Network & Linking Data Centres

How Zayo is expanding fibre network & linking data centres. Zayo teams up with Reintel to deliver high-capacity fibre links between Spain and Portugal, strengthening data centre connectivity across Iberia Zayo Europe has entered the Iberian market by way of a new partnership with Reintel, Spain's largest dark fibre operator. The deal expands Zayo's 400GE-enabled wavelength and Tier-1 IP network into Spain and Portugal, linking the region's growing data centre clusters to its wider European infrastructure. "This partnership marks another important step in Zayo Europe's journey to connect the continent's most dynamic markets," says Colman Deegan, CEO at Zayo Europe. "Spain and Portugal are quickly emerging as major data centre hubs, with a strong supply of renewable energy driving new investments to power AI and other cutting-edge technologies." Fibre routes connect Iberia's key digital markets. The new network spans more than 3,500km of fibre, linking Madrid, Lisbon, Barcelona, Bilbao and Sines. These routes offer low-latency, high-capacity connections designed to support data centres and enterprises operating at scale. Zayo's European footprint already includes more than 600 data centres. By adding Iberia to its network, Zayo allows faster deployment of cloud services and enables seamless DC-to-DC (data centre to data centre) connectivity across the continent. Colman says: "Data Centre Magazine is delighted to partner with Reintel, who operate the highest quality, mission critical fibre infrastructure in the region. "By extending our network through their low latency, high availability fibre routes, we're enabling enterprises, data centres and carriers across Iberia to access our extensive high-performance connectivity that underpins Europe's innovation economy." Following its expansion in Germany, Zayo adds Iberia as a key strategic link. With new data centres planned in 2026, Zayo positions its infrastructure to meet future digital demands in southern Europe. Colman says: "Following our recent expansion in the German Market, Iberia becomes the next strategic link in furthering the reach of our pan-European network. With the significant DC rollout planned in 2026, Zayo Europe is poised to set connectivity trends for the decade ahead." Infrastructure meets digital and cloud growth. Reintel operates a nationwide dark fibre network across Spain, offering the scale and availability required by hyperscale operators, cloud providers and digital platforms. Its infrastructure is suited for high-throughput services and latency-sensitive applications. Zayo's wavelength and IP solutions are already supporting enterprise traffic in major European regions. The Iberian build links to subsea systems in both the Atlantic and Mediterranean, enabling new long-haul routes to other parts of Europe and beyond. Francisco J. Blanca Patón, CEO at Reintel, says: "Zayo Europe's expansion into Iberia aligns perfectly with its mission to accelerate Spain's digital transformation. "Combining our extensive dark fibre footprint with Zayo Europe's international network and unparalleled service excellence creates powerful opportunities for customers across the region." Iberia continues to attract data infrastructure investment due to its renewable energy access and coastal landing points for subsea cables. These advantages make it a strategic location for new data centres and intercontinental network links. High-capacity fibre fuels regional data centre growth. With hyperscale data centre developments scheduled across Spain and Portugal through 2026, demand is rising for resilient fibre infrastructure. The Zayo-Reintel partnership helps meet this demand by providing high-availability routes for carriers, operators and cloud-based services. Reliable fibre connectivity is critical for Data Centre operators seeking to scale AI, edge and content workloads across multiple sites. High-performance links allow seamless movement of data between data centres and faster delivery of services to end users. "This partnership will empower data centres and businesses across Spain and Portugal to keep pace with rising data demands and ultimately, strengthen Europe's digital backbone," explains Francisco. Zayo's entry into Iberia connects two expanding data markets to its pan-European network. The agreement adds capacity, reach and performance for customers looking to scale digital services, cloud platforms and AI-driven workloads across the region.
