As global internet traffic continues to grow, organisations are looking beyond traditional connectivity hubs to improve network performance, reduce latency and support expanding digital services. One location gaining increasing strategic importance is the Iberian Peninsula, where international subsea cables, regional carrier networks and digital infrastructure converge.
At the centre of this ecosystem is ESpanix, one of Southern Europe’s largest and longest-established Internet Exchanges (IX). Through Epsilon’s global backbone and Infiny Network as a Service (NaaS) platform, organisations can remotely peer with ESpanix without deploying infrastructure in Spain, making it easier to expand globally while improving network performance.
Whether you’re a service provider, cloud provider, enterprise or content platform, remote peering with ESpanix offers a scalable way to optimise connectivity across Europe, Africa, the Middle East and the Americas.
What is ESpanix?
ESpanix is a leading internet exchange and digital hub in Southern Europe and the oldest in Spain. It operates across interconnection, data centre and value-added services, with infrastructure strategically located in Madrid and Barcelona.
Its ecosystem includes a high concentration of internet service providers, carriers and content networks. This enables direct traffic exchange between networks, reducing reliance on upstream transit providers and improving overall network efficiency.
For organisations looking to expand into Southern Europe or optimise existing routes, ESpanix provides a well-connected and strategically positioned entry point.
What is Remote Peering?
Remote peering enables organisations to connect to an Internet Exchange without installing networking equipment inside the exchange facility.
Instead of building local infrastructure, businesses connect securely through an established network provider such as Epsilon. This provides access to the same peering ecosystem while reducing deployment costs, operational complexity and implementation time.
Why the Iberian Peninsula Matters for Connectivity?
Southern Europe, and specifically the Iberian Peninsula, is increasingly important in global network architecture due to its geographic position between three major regions: Europe, Africa, and the Americas. Spain and Portugal together serve as a natural aggregation point for subsea cable systems connecting these continents.
This makes the Iberian Peninsula a critical routing and interconnection zone for international traffic flows. By peering at ESpanix, organisations can optimise cross-border routing, reduce latency, and improve application performance across multiple regions. The peninsula’s central position links global markets via terrestrial links and submarine cables landing in Barcelona, Valencia, AlmerÃa, Lisbon and Bilbao.
When combined with Epsilon’s high-capacity global backbone across Asia, the Middle East, and other key markets, this creates a powerful connectivity pathway between Asia, Southern Europe, and emerging markets in Africa and the Americas, supporting growing demand for resilient, high-performance global network infrastructure.
What are the Benefits of Peering at ESpanix via Epsilon?
| Benefits | What it means | Why it matters |
| High-density interconnection | Direct access to ISPs, carriers, and content providers | Fewer hops, more efficient routing |
| Low latency | Optimised routing within Madrid, Barcelona, and wider Europe | Supports real-time apps, cloud services, latency-sensitive workloads |
| Resilient infrastructure | Tier IV compliant data centres across two cities (Madrid and Barcelona) | Built-in redundancy and high availability |
| Seamless Remote peering | No local infrastructure needed | Lower cost, faster deployment, more flexibility to scale as business needs evolve |
| Global reach | Epsilon’s backbone spans Asia, the Middle East, and Africa | One connection point for multi-region traffic exchange |
Why Low-Latency Connectivity Matters?
Modern digital services increasingly depend on low-latency, high-reliability connectivity. Applications such as Artificial Intelligence (AI) workloads, real-time analytics, cloud-native platforms, and collaboration tools require consistent performance to function effectively.
By peering at ESpanix via Epsilon, organisations gain access to optimised routing paths, dense interconnection environments, and resilient infrastructure. This combination supports high-performance application delivery while ensuring scalability for future growth.
As AI-driven and data-intensive applications continue to grow, proximity to key interconnection hubs like ESpanix in Madrid and Barcelona becomes a critical factor in network strategy.
Building Smarter Connectivity with ESpanix via Epsilon
Accessing ESpanix through Epsilon enables organisations to simplify peering, improve network efficiency, and extend global reach without the complexity of physical infrastructure deployment.
Whether the objective is to optimise traffic flows between Europe, Africa, and the Americas, enhance connectivity within the Iberian Peninsula, or expand into global markets, Epsilon provides seamless remote access to one of Southern Europe’s most important interconnection hubs.
