Netrality 900 Walnut St Louis: 10MW Carrier Hotel & Colocation Hub Missouri

Status: Fully Operational Carrier Hotel & Interconnection Gateway   |   Location: 900 Walnut Street, St. Louis, MO 63101, Missouri, United States


Project Overview

Netrality's 900 Walnut Street is the premier carrier hotel and network interconnection facility in St. Louis, Missouri, serving as one of the Midwest's most important digital infrastructure and connectivity hubs. Strategically located in the heart of downtown St. Louis, the facility encompasses approximately 110,000 square feet of purpose-built technical space that supports enterprise colocation, regional cloud platforms, telecommunications infrastructure, financial services, government agencies, healthcare organizations, and mission-critical business applications. Positioned at the intersection of major Midwestern fiber routes, 900 Walnut functions as a critical interconnection gateway linking networks across the eastern, western, northern, and southern United States. The facility provides direct access to more than 43 network providers, multiple diverse dark fiber corridors, internet service providers, and Netrality's highly connected Meet-Me Room (MMR), enabling customers to establish low-latency, carrier-neutral interconnections while supporting hybrid and multi-cloud architectures. Engineered for high availability, the data center incorporates resilient utility power infrastructure, redundant electrical distribution systems, uninterruptible power supply (UPS) systems, backup generators, advanced fire detection and suppression technologies, intelligent building management platforms, and energy-efficient cooling solutions capable of supporting high-density enterprise and AI-ready computing environments. Multi-layer physical security, including controlled access, continuous surveillance, and 24/7 operational monitoring, ensures comprehensive protection for mission-critical infrastructure. As a carrier-neutral ecosystem, the facility allows enterprises, cloud providers, content delivery networks, and telecommunications operators to deploy scalable digital infrastructure with flexible connectivity options and direct access to regional and national fiber networks. Its strategic location within one of the United States' most significant telecommunications crossroads makes 900 Walnut an ideal platform for disaster recovery, business continuity, cloud connectivity, and latency-sensitive applications. By combining resilient engineering, rich interconnection density, scalable colocation services, and exceptional network diversity, Netrality's 900 Walnut Street continues to play a pivotal role in supporting digital transformation and the expanding connectivity requirements of organizations throughout the Midwest and beyond.
