Michigan-based Internet Service Provider (ISP) 123Net has expanded its data center in Detroit. Located at 24700 Northwestern Highway in the Southfield area of Detroit, DC1 offers 80,000 sq ft (7,432 sqm) of colocation space. The site has up to 20MW of available utility power. The expansion reported added colocation space and infrastructure tailored for the demands of AI inference and other data-intensive applications, allowing for liquid-cooled GPUs to be installed.
“Big News! 123Net has completed a major expansion of its Southfield DC1 Data Center, adding 4MW of new power, advanced colocation space, and direct access to the Detroit Internet Exchange, the company said this week. “This makes DC1 the only facility in Michigan where massive GPU power meets free peering, cutting network costs and creating the ultimate environment for AI, machine learning, and data-intensive applications.”
“Having the Detroit Internet Exchange inside the data center gives our clients instant access to a powerful peering ecosystem and a more direct path to end users,” said Dan Irvin, founder and CEO of 123Net. “It’s the only place in Michigan where massive GPU power meets free peering, significantly cutting network costs compared to traditional colocation.”
