Interxion Holding NV

Interxion, also known as Interxion Holding NV, is a European provider of carrier‑neutral data center and colocation services. The company supplies secure floor space, power, cooling and network connectivity to enterprises, cloud providers and telecommunications operators that require reliable infrastructure for their IT workloads. Its facilities enable customers to house servers, storage and networking equipment while maintaining direct links to a broad ecosystem of carriers, internet exchanges and cloud platforms. Interxion primarily serves markets across Europe, offering localized solutions that meet the latency, sovereignty and compliance requirements of regional businesses.

A distinguishing attribute of Interxion is its focus on carrier‑neutral environments, which allows customers to interconnect with multiple network providers without being locked into a single vendor. This neutrality supports hybrid cloud strategies and facilitates low‑latency access to financial trading hubs, content delivery networks and public cloud on‑ramps. The firm also emphasizes high standards of operational resilience, adhering to recognized industry certifications, which underpin its reputation for security and reliability. Its data centers are designed to accommodate dense power loads and advanced cooling techniques, catering to the growing demands of high‑performance computing and artificial intelligence workloads.

Structurally, Interxion Holding NV was an independent publicly listed company headquartered in the Netherlands before being acquired by Digital Realty, a global data center real estate investment trust, in 2019. Following the acquisition, Interxion operates as a subsidiary within Digital Realty’s International division, retaining its brand and operational focus on the European market while benefiting from the parent’s financial resources and global scale. The Dutch headquarters continues to oversee regional strategy, sales and engineering functions for the European footprint.

In December 2015 Interxion experienced a security incident in which unauthorized access to its customer relationship management system exposed business contact details—including names, titles, email addresses and phone numbers—for approximately 23,200 individuals. The breach did not involve the theft of more sensitive data such as financial records or passwords, but it prompted the company to notify affected parties and heightened awareness of phishing risks leveraging the exposed information. The episode underscored the importance of protecting ancillary systems even within organizations whose core business revolves around physical and network security.
