Vantage Data Centers plans to invest $1 billion to build a new data center campus in Ashburn, Va.

Vantage secured 42 acres for the 108-MW wholesale data center campus in Ashburn's "Data Center Alley," the company said in a release. The campus, set to comprise five buildings totaling over 1 million square feet, represents the company's largest expansion to date.

The company expects to start construction on the project in early 2018, and the first of the five planned buildings is slated to total 24 MW of capacity.
