Digital Realty Expands to Lisbon for Subsea Data Centre

Lisbon acts as Europe’s Atlantic gateway, providing low-latency connectivity to the Americas. The Lisbon facility supports up to 2.4 MW of IT load. Several strategic network service providers are already connected, giving the site immediate interconnection value.

Portugal is positioned on the Iberian Peninsula and is gaining attention as a digital and interconnection hub. Industry investment in subsea cable infrastructure supports this position. Portugal connects Europe with North America, South America, Africa, the Middle East and Asia through these systems.

Subsea proximity and reduced latency

Previously, subsea-related deployments route through Digital Realty’s facilities in Madrid. By establishing a facility in Lisbon, the company reduces latency and positions infrastructure closer to cable landing stations.

The selected site is the closest data centre to the submarine cable landings in Carcavelos. This enables support for landing solutions and the hosting of termination equipment for subsea cable infrastructure.

Portugal is the only location in Europe with direct subsea connectivity to South America. It also serves as a gateway for West Africa and adds route diversity to the Mediterranean subsea network. Route diversity reduces the risk of disruption by providing alternative paths for traffic. Sixteen subsea cables land in Portugal, most near Lisbon.

Paula Cogan, Managing Director of EMEA at Digital Realty, says: “Adding Portugal to our portfolio represents a key piece of our Iberian strategy.

“This expansion strengthens interconnection across our platform and gives customers unparalleled choice and agility as they scale their businesses globally.”

Paula highlights the role of Lisbon in strengthening interconnection across Digital Realty’s platform. The company’s model centres on PlatformDIGITAL, its global data centre platform that enables customers to deploy infrastructure in multiple metros while maintaining consistent connectivity and operational standards.
