The Scottsdale-based company, which provides domain name registration and auxiliary services, plans an additional $8.5-million investment for upgrades to the 1402 E. Buckeye Rd. property. The upgrade will focus on the 117,000-sf Building C, which is to be retrofitted into a data center for Web hosting. The project's completion is scheduled for March, delivering Go Daddy's second data center in the area. The other facility is about five miles away at 4041 N. Central Ave., also in Phoenix.

There are no immediate plans for the 127,000-sf Building B and the 75,000-sf Building A. At some point, the smaller structure will be demolished to make way for a parking lot.

The 11-acre property, which rose as a Sears distribution center, was acquired by the seller, Sterling Buckeye Network Exchange LLC, in 2000. Sterling upgraded and retrofitted the complex, targeting telecommunications companies as prospective tenants.
