Spain

A Southern European Hub At The Crossroads Of Transatlantic And Mediterranean Undersea Cables

Spain is emerging as a strategic gateway for data flows between Europe, the Americas, Africa, and the Middle East. Its geographic location on the Iberian Peninsula makes it a natural hub for international networks, with some 30 active submarine cables, including MAREA (Microsoft/Meta, 6,600 km to Virginia) and Grace Hopper (Google, 16 fiber pairs to New York). Madrid accounts for the majority of the country’s colocation offerings, followed by Barcelona, while Aragon is emerging as a hyperscale hub thanks to its renewable energy resources and support from local governments. The Spanish market is home to international colocation providers such as Equinix, Digital Realty, CyrusOne, Global Switch, Data4, and NTT DATA, alongside local players like Nabiax and Adam Ecotech. The internet exchange points DE-CIX Madrid, DE-CIX Barcelona, ESpanix, and CATNIX ensure dense local and regional peering. Energy costs benefit from renewable power purchase agreements (PPAs) that are competitive on a European scale, supported by a national investment plan of more than 6 billion euros per year to modernize the power grid through 2030. The Spanish regulatory framework is aligned with European law on data protection (GDPR) and digital governance. The España Digital 2025 and 2026 agendas direct public investment toward the deployment of 5G, the digital transformation of businesses, and the strengthening of connectivity infrastructure throughout the country.

Climate

Spain has a remarkable variety of climates. Madrid has cool winters (an average of 6°C in January) and very hot, dry summers (an average of 26°C in July, with frequent highs above 38°C), with low relative humidity of around 45% in the summer. Barcelona enjoys a more temperate Mediterranean climate (10°C in winter, 24°C in summer) but with higher humidity. The North Atlantic region (Bilbao) offers mild temperatures year-round (8 to 20°C) with high humidity. For data centers, the central plateau offers significant potential for free cooling during the winter months thanks to the dry, cool air. However, the scorching summers require extensive use of mechanical air conditioning. The northern regions allow for more extensive free cooling throughout the year, promoting an optimized PUE. Operators are increasingly investing in liquid cooling solutions to meet the growing densities of AI and HPC workloads.

Transport

Spain has a dense airport network, including Madrid-Barajas (a major intercontinental hub, located about 15 km from downtown) and Barcelona-El Prat (offering European and international connections, located about 15 km from downtown). Bilbao, Valencia, Málaga, and Seville round out the regional air network. The AVE high-speed rail network connects Madrid to Barcelona in 2 hours and 30 minutes, to Seville in 2 hours and 30 minutes, and to Valencia in 1 hour and 40 minutes, facilitating travel between the main data center hubs. The highway network connects major urban centers and serves the outlying industrial areas where data center campuses are concentrated, particularly around Madrid (Alcobendas, Alcalá de Henares, San Sebastián de los Reyes) and in Aragon (Zaragoza). The land connection to Portugal and France ensures network continuity with the hubs in Lisbon and Marseille.
