CoreSite has announced native 400 Gbps (400G) Amazon Web Services (AWS) Direct Connect at its Chicago data center campus. CoreSite says the new port speed targets high-bandwidth, performance-intensive workloads, including enterprise and AI applications, and GPU-optimized neocloud providers built for large-scale AI training, inference, and agentic automation.
The company positions the Chicago campus as a low-latency on-ramp to AWS using AWS Direct Connect at 400G. “The AI economy developing within CoreSite’s data centers demands a high-level of interoperability between enterprises, AI applications, neoclouds and public cloud providers,” said Juan Font, President and CEO of CoreSite and SVP of American Tower. “Enabling native 400G AWS Direct Connect at CoreSite’s Chicago campus gives our customers the unique ability to establish low-latency, high-bandwidth data pipelines that deliver consistent performance, enhanced security and seamless integration across their digital environments.”
CoreSite reports that customers in data-intensive industries are already using 400G connectivity, including “one leading cybersecurity provider” using AWS 400G Direct Connect to process large data volumes and accelerate real-time threat analysis. It also notes that financial services firms are evaluating 400G for latency-sensitive trading and quantitative research.
CoreSite also says its Chicago campus provides dense fiber access and high-density colocation capacity to support hybrid IT modernization and operationalizing AI at scale. The company claims that using direct interconnection can provide data replication savings of up to 70%, and that customers “can eliminate data egress costs when restoring data from certain local cloud availability zones,” with cost-savings caveats noted in the release.
CoreSite says it now hosts three locations with 400G AWS Direct Connect: Chicago, Illinois; Santa Clara, California; and Reston, Virginia.
