XMission Data Center Salt Lake City: 51 E 400 S Downtown Colocation Utah Specs
Status: Operational | Location: 51 East 400 South (Corner of 400 South & State Street / 67 E 400 S), Salt Lake City, UT 84111, Utah, United States
Project Overview
The XMission Data Center, located at 51 East 400 South in downtown Salt Lake City, Utah, is a prominent regional colocation, managed hosting, and network interconnection facility serving enterprises, technology companies, telecommunications providers, and organizations throughout the Intermountain West. Operated by XMission, one of Utah’s pioneering independent Internet Service Providers, the facility forms an important part of the region’s digital connectivity ecosystem and functions as a core peering gateway through its hosting of the Salt Lake Internet Exchange (SLIX). The presence of SLIX enables participating networks and service providers to exchange traffic locally, helping reduce routing distances and latency while improving the efficiency of regional internet connectivity. The facility provides flexible colocation options, including high-density full cabinets, partial cabinets, and customized private cages, allowing customers to select infrastructure configurations based on their computing, security, and space requirements. Its power architecture incorporates true A+B redundant electrical infrastructure, providing independent power paths designed to improve resilience and maintain service continuity for mission-critical equipment. This configuration is particularly valuable for organizations operating servers, networking equipment, cloud infrastructure, and other systems that require high levels of availability. The data center also offers low-latency direct carrier peering, enabling customers to establish efficient network connections with telecommunications carriers and other interconnected networks while reducing dependence on remote internet exchange locations. This connectivity environment supports applications ranging from enterprise networking and managed hosting to cloud access, content delivery, and distributed digital services. Sustainability is another component of the facility’s operating model, with 100% renewable power offsets supporting customers seeking to reduce the environmental impact associated with their digital infrastructure. By combining carrier connectivity, internet exchange access, redundant power infrastructure, flexible colocation, managed hosting, and renewable energy support, the XMission Data Center serves as an important regional digital infrastructure hub. Its downtown Salt Lake City location and strong interconnection ecosystem enable organizations to deploy reliable computing infrastructure close to regional businesses and network participants while maintaining efficient access to broader national and global connectivity routes.
