St. Louis-Walnut

The Walnut Data Center includes over 4,000 square feet of raised floor space. The facility is monitored 24/7, and has redundant, enterprise class routers running BGP to support bandwidth throughput needs- all while maintaining stringent security requirements. With redundancy prioritized in the network infrastructure, UPS battery backup, and onsite generators, the Walnut facility is protected from potential outages and can remain fully operational for an indefinite period of time. It’s audited under ITAR, EU-US Privacy, SOC 1, SOC 2, HIPAA, GLBA, and PCI Colo* standards annually.
