The unfinished office campus is just east of Interstate 17 and just north of the under-construction Loop 101 Freeway, which will link north Phoenix and north Scottsdale to the freeway system for the first time when it opens late next year. A number of corporations and developers have begun office projects in the area over the past two years.

Atlanta-based Cox Communications officials say that they determined that is was a wiser move to put the undisclosed amount of money into upgrading its Phoenix-area network. The campus was to have several hundred thousand sf of office space. Cox did not disclose the asking price for the property.

Cox, which has about 600,000 subscribers in the Valley, has had to deal with a number of technical issues with its service in the past two years, including network outages, service problems and the resignation of its longtime local manager.

Subscribers to Cox's @home high-speed Internet service have randomly been denied access to the Web for the past month. Last fall, a programming changed knocked out certain channels for hundreds of customers. The 600,000 subscribers that Cox had this time last year has dwindled to about 15,000.
