INTERXION HOLDING NV (NYSE: INXN), a leading European provider of carrier and cloud-neutral colocation data center services, today announced that it will construct its ninth data center on its Frankfurt campus (“FRA 9”) in response to customer demand. FRA 9, which is scheduled to be operational in the first quarter of 2014, will be built in a single phase and will provide approximately 800 square meters of Equipped Space and 1MW of customer-available power. “Demand for our products and services continues to be strong in Frankfurt, supported by our Communities of Interest approach and bolstered by the stable German economy. We are experiencing growth across multiple segments, including cloud providers, financial services, and digital media,” said David Ruberg, Interxion’s Chief Executive Officer. “FRA 9 will enable us to bring capacity on-line ahead of our previously announced FRA 8 expansion, which will ensure that we are able to meet our customers’ requirements.” The capital expenditure associated with FRA 9 is approximately €13 million. The site, which is secured by a long-term lease, will access existing campus power and will leverage the high connectivity available at Interxion’s Frankfurt campus. The anticipated capital spend in 2013 is included in the 2013 capital guidance previously provided by the Company. In response to continued demand, Interxion is also accelerating the availability of the second phase of its previously announced FRA 8 new build. The revised schedule has the second 900 square meter phase scheduled to be operational in the second half of 2014 instead of 2015. The first phase is on schedule to be available in the first half of 2014.
