Equinix ST3 Santiago IBX Data Center: Downtown Carrier-Neutral Colocation Hub
Status: Fully Operational Carrier-Neutral IBX Facility | Location: Pasaje Nueva Amunátegui 26, Office 105, Santiago, Región Metropolitana, 8340519, Chile
Project Overview
Equinix ST3 is a premier International Business Exchange (IBX) carrier-neutral colocation data center strategically located at Pasaje Nueva Amunátegui 26 in the heart of Santiago, Chile. Originally developed by Entel and incorporated into the Equinix portfolio following its acquisition in 2022, the facility occupies a prime location adjacent to the iconic Entel Tower and Santiago's government and financial district, positioning it as one of Chile's most important digital infrastructure hubs. Purpose-built to support mission-critical enterprise applications, financial services, telecommunications, cloud computing, content delivery, and public sector workloads, ST3 provides a highly secure, resilient, and network-dense environment for organizations requiring reliable, low-latency digital infrastructure. As a carrier-neutral facility, the data center offers customers access to a diverse ecosystem of telecommunications providers, internet service providers, network operators, and digital service partners, enabling flexible connectivity and network redundancy. ST3 functions as a primary network exchange point within Chile, connecting enterprises, financial institutions, government agencies, and multinational organizations to major global cloud platforms, international subsea cable systems, regional internet exchanges, and extensive carrier networks through Equinix Fabric and Metro Connect services. The facility is engineered with resilient electrical and mechanical infrastructure, redundant utility feeds, energy-efficient cooling systems, uninterruptible power supply (UPS) systems, backup generators, enterprise-grade physical security, continuous environmental monitoring, and 24/7 operational support to ensure maximum service availability for mission-critical operations. Through its rich interconnection ecosystem and seamless integration with Equinix's global platform, ST3 enables businesses to deploy hybrid and multi-cloud architectures, accelerate digital transformation initiatives, improve disaster recovery capabilities, and achieve secure, high-performance connectivity to customers and partners throughout Latin America and international markets. As a key gateway between Chile's digital economy and the global internet ecosystem, Equinix ST3 delivers a scalable, future-ready colocation platform that supports the continued growth of cloud adoption, enterprise modernization, and next-generation digital services.
