Mar 12, 2026 Eric Bell World
Go to PodcastQBE North America ran a data center on its former General Casualty campus in Sun Prairie, northeast of Madison, which became one of QBE's two global data centers. A later project combined the original two data rooms into one larger room with A and B UPS systems, N+1 standby generation and hot and cold aisle containment, completed while the room stayed live.
QBE sold the campus to Derby District Holdings in October 2025. The new owner markets the former data center space in Building 300, with raised floors, battery and generator backup and multiple fiber providers, as part of its Derby District redevelopment.
