INTERXION OSTERREICH GmbH (Interxion), a wholly-owned subsidiary of INTERXION HOLDING NV (NYSE: INXN), a leading European provider of carrier-neutral data centre services, today announced that it has completed the first phase of a two-phased capacity expansion project in the Vienna metropolitan area bringing 600 square metres of equipped space to a rapidly-growing market. Once both phases of the project are complete, Interxion will house 4,700 sqm of available equipped space at its Vienna data centre. The two phased project represents a €12 million investment that secures Interxion’s position as Austria’s premier carrier-neutral colocation provider. Initially announced in May 2011, the expansion of Interxion’s Vienna data centre addresses the high degree of capacity utilisation at the site. Since September 2, 2011, initial customers have already begun to install their equipment to help reduce the cost of their network access and improve their business performance. "Through our ongoing expansion programme, we offer our customers the broadest coverage across Europe and ensure our continued ability to provide robust connectivity options, value proximity to business partners and real time applications for new and existing customers,” said David Ruberg, Interxion’s Chief Executive Officer. The Vienna data centre expansion is an important component of Interxion’s growth strategy and reflects the Company’s ongoing commitment to long-term growth opportunities that meet European market demand. This year, Interxion has announced nearly 8,000 sqm in additional equipped space, all of which is scheduled to become operational by the middle of 2012. Interxion is adding this capacity through new facilities and upgrades in markets with strong demand, including London, Paris, Dusseldorf, Stockholm, Vienna, and Dublin. The Vienna data centre will service new market demand from cloud services, digital media, enterprise and financial sectors. In addition, the enhanced data centre will continue to be an ideal gateway to the Central and Eastern European (CEE) region for international customers. Currently, the data centre has more than 90 carriers present in the data centre, 21 of which serve 12 countries in the CEE region with more than 130 connectivity options.
