CoreSite, a subsidiary of American Tower, has expanded its presence in the New York metropolitan area with the launch of its newest facility, NY3. The purpose-built data center, located in Secaucus, New Jersey, adds more than 138,000 square feet to CoreSite’s regional portfolio and is positioned directly adjacent to the company’s existing NY2 site. Together, NY2 and NY3 create one of the most interconnected and scalable data center campuses on the U.S. Eastern Seaboard.
The addition of NY3 brings CoreSite’s total New York footprint to more than 442,000 square feet, including the company’s NY1 location at 32 Avenue of the Americas in Manhattan, alongside NY2 and the newly opened facility in Secaucus.
The campus delivers direct connections to Amazon Web Services (AWS) and is home to a diverse ecosystem of enterprises across sectors such as global financial services, higher education, and telecommunications. By leveraging CoreSite’s Open Cloud Exchange, customers gain access to all major public cloud providers, as well as high-count dark fiber interconnections for scaling workloads across CoreSite’s nationwide platform.
In addition to scale and connectivity, NY3 and NY2 are equipped to support advanced liquid cooling technologies, providing the efficiency required for compute-intensive AI and high-performance workloads. This positions the facilities to serve organizations adopting hybrid IT strategies that increasingly rely on colocation for generative AI applications. According to the 2025 State of the Data Center Report, cloud interconnection is now the leading driver for colocation adoption, followed by high-density power and cooling capabilities, cost efficiency, compliance, and security.
AI and Advanced Workloads
CoreSite has already enabled deployments at NY3 across financial and technology verticals. These include high-density trading and research environments that demand low-latency connectivity to exchanges, cloud service providers scaling their footprint in the Northeast, and enterprises running both trading and production applications. The facility was selected for its reliability, strong interconnection capabilities, and future-proof scalability.
Adam Post, Senior Vice President of Finance and Corporate Development at CoreSite, emphasized that the new site reflects a broader strategy to anticipate the needs of customers navigating digital transformation. “The launch of NY3 represents more than just added capacity; it’s a strategic investment in our customers’ future,” said Mr. Post. “As AI and advanced workloads reshape industries, enterprises need infrastructure that is purpose-built for performance and scalability along with robust interconnectivity solutions. NY3 delivers on that promise and will empower our customers in the New York market to innovate, connect, and grow with confidence.”
The facility’s completion also marks a key milestone in CoreSite’s national expansion strategy. The company now operates 30 data centers across 11 major U.S. markets, representing approximately 4.5 million square feet of colocation and interconnection space. By pairing scalable infrastructure with direct access to cloud ecosystems, CoreSite aims to position itself as a central enabler for enterprises deploying AI-driven and high-performance workloads across distributed architectures.
