The SDN Communications Data Center is expanding.

The SDN Data Center, located northwest of Sioux Falls city limits, serves as a switch site location, co-location facility, data center, disaster recovery site, and point of presence.

Built with 12-inch-thick concrete walls, it's able to withstand South Dakota's severe weather season.

Construction crews broke ground in the fall of 2021 to double the size of the existing data center space by adding a second pod to the west of the current facility. Now SDN is seeking tenants to lease space, which can be built to suit your needs.


It's the type of facility our customers expect SDN to have to ensure constant connectivity services. That’s UPTIME.
― Ryan Punt, CEO | SDN Communications

First opened in 2012, SDN built the multi-million-dollar facility as an emergency backup for our now 50,000-mile fiber network, which supports critical business, government data operations and the networks of our 17 owner companies.

Engineers researched climate conditions and worked with the National Oceanic and Atmospheric Administration (NOAA) to choose the best location based on historical weather patterns.

The 66-acre site also has easy access to both major South Dakota Interstates (I-29 and I-90).
