Silicon Valley Market Expansion

The massive scale of the Santa Clara campus is coupled with the availability of native cloud onramps in the heart of some of the largest concentrations of internet and technology companies in the world. These qualities uniquely enable CoreSite to support a broad range of colocation use cases from enterprises and digital platforms. Through the Open Cloud Exchange^® (OCX), CoreSite’s leading software-defined networking platform, customers utilize the superior interconnection needed to reach new markets, rapidly scale on-demand, reduce total cost of operation and accelerate IT modernization. The OCX is uniquely suited to meet the most demanding compute needs of digital platforms with a rich ecosystem of 205 cloud, network and IT service providers available.

SV9 Construction Milestones Achieved

Construction of SV9 has progressed since securing building permits in 2022. CoreSite has completed building the structural steel and concrete pours for the facility. Despite experiencing historically rainy and windy weather conditions in the Santa Clara area, the company remains on schedule for completion of SV9 in 2024 with its first phase ready for occupancy in Q1 2024.

Strategically located in downtown Denver, CoreSite’s DE1 and DE2 data center facilities deliver two network-rich data centers and the region’s largest peering exchange. CoreSite sits at the nexus of where the networks meet in the Rocky Mountain region and is home to a rich interconnected ecosystem of nearly 150 organizations comprised of cloud, network and IT service providers.
