In 2007, we announced plans to construct a data center in Council Bluffs. Then in the spring of 2012, we announced that we would be building a second facility. We’ve established a long-term commitment to the region and state and will have invested over $2.5 billion by 2019. We’ve created over 300 jobs on site so far, and we work hard to support the communities in which our employees live and work.
