Cogent St. Louis Data Center: Tier 1 IP Transit & Colocation Hub 900 Walnut MO

Status: Fully Operational Carrier Node & Enterprise Colocation Facility   |   Location: 900 Walnut Street, St. Louis, MO 63101, Missouri, United States


Project Overview

Cogent's St. Louis Data Center is strategically located within the 900 Walnut Street carrier hotel in St. Louis, Missouri, one of the Midwest's most significant telecommunications and network interconnection facilities. Serving as a major Tier 1 optical network routing node within Cogent Communications' global backbone infrastructure, the facility plays a vital role in delivering high-performance connectivity, enterprise colocation, IP transit, and cloud networking services to businesses, telecommunications providers, internet service providers, financial institutions, content delivery networks, and government organizations. Positioned within the highly carrier-dense environment of 900 Walnut, the data center benefits from direct access to numerous domestic and international network operators, enabling customers to establish low-latency, carrier-neutral interconnections with exceptional network diversity and resilience. The facility provides enterprise-grade colocation services, high-bandwidth IP transit, wavelength services, and low-latency dark fiber connectivity, supporting mission-critical applications, hybrid cloud deployments, disaster recovery solutions, and high-performance enterprise workloads. Engineered for maximum reliability, the data center incorporates redundant utility power feeds, uninterruptible power supply (UPS) systems, backup generator infrastructure, advanced cooling technologies, intelligent environmental monitoring, and comprehensive fire detection and suppression systems to ensure continuous operational availability. Multi-layer physical security, including controlled access systems, continuous surveillance, and 24/7 operational support, safeguards customer infrastructure and sensitive data. Through Cogent's extensive optical backbone, the facility provides direct fiber connectivity linking St. Louis with major metropolitan markets including Chicago, Kansas City, and other key North American internet exchange points, enabling fast, reliable, and scalable communications across regional and international networks. Its strategic location at the crossroads of major fiber corridors makes the facility an ideal platform for latency-sensitive applications, cloud connectivity, financial services, content distribution, and enterprise digital transformation. By combining resilient infrastructure, Tier 1 global network connectivity, carrier-neutral interconnection, and high-capacity optical transport services, Cogent's St. Louis Data Center serves as a critical digital infrastructure asset supporting the expanding connectivity and data processing needs of organizations across the Midwestern United States and beyond.
