A US managed services provider (MSP) is set to expand a data center in Texas.

A filing with the Texas Department of Licensing and Regulation (TDLR) shows Rack Asset Realty, LLC plans to add and upgrade existing white space at a site in Dallas.

The company has filed plans to remodel offices and a data center area at 4939 Reading Street in Dallas County for a new 20,000 sq ft (1,860 sqm) data center development.

The $1.4 million project will run from September 2025 to September 2026.

Erward Osckar is listed as the owner of Rack Asset Realty, LLC. Osckar is also the founder and CEO of Seattle-based MSP Wowrack.

An old JLL sales brochure suggests the single-story building in Dallas was previously a T-Mobile switching site (likely inherited from Sprint). Built in 1956 and set on less than 1 acre, the 372-rack site was on sale for $2.9 million. It was listed as equipped with 1MW of generator capacity.

When T-Mobile exited the site and the facility was sold is unclear.

Founded in 2001, Wowrack currently operates out of a Sabey-owned data center in Seattle, Washington, at the latter’s Intergate West Campus. The firm offers colocation as well as managed IT, network, cybersecurity, and cloud services.

According to the company’s website, Wowrack originally operated out of Osckar’s home, starting with just six servers.

The company previously operated out of Digital Realty’s Westin Building in Seattle before relocating to Sabey’s facility at 12201 Tukwila International Blvd in Tukwila. It also has an Indonesian subsidiary and offers services through the CloudRaya, ServerStadium, ColoinSeattle, and Wownet brands.

T-Mobile acquired Sprint for $26 billion in 2018, closing the deal in 2020. Since then, a number of vacant or soon-to-be vacant former Sprint data centers occupied by T-Mobile have come onto the market over the past several years.

Small facilities in Texas, Florida, Iowa, Tennessee, and Maryland have been listed for sale or lease - many stating that T-Mobile was exiting the sites due to already having data centers in the area.

Separately, T-Mobile sold its Wireline business to Cogent Communications for just $1 in September 2022. Much of the business sold to Cogent was Sprint‘s legacy US long-haul fiber network, with Cogent converting dozens of inherited Sprint switch sites into colocation facilities.

T-Mobile recently filed to upgrade an existing data center in McAllen, Texas, to host 5G equipment.
