(Ted Houston, KFYI News) Go Daddy, the Scottsdale-based internet domain hosting firm whose clients are mostly small businesses, announced on Tuesday that it's making a major expansion.

At a news conference on an empty lot in the ASU Research Park at Loop 101 and Warner Rd., Gov. Jan Brewer announced that Go Daddy will build a 150,000 square foot data and technology center on the parcel where the announcement was held.

CEO Blake Irving said that the company will move from a 75,000 square foot facility elsewhere in Tempe to the new facility once it opens next spring.

"We'll take that 75,000 square feet that we're in today, move those folks here, and then expand, basically doubling the work force here in this facility," he said. "We'll hire over 2014 probably 500 new employees, in engineering ranks, development ranks, design ranks, and customer care."

It's the second announcement in recent months that will result in hundreds of new jobs for Tempe. In March, Brewer announced that California-based Union Bank will open a customer service center just north of downtown Tempe, creating 200-300 jobs.
