Press Release 03 Mar 2017 DUBLIN – Friday 3rd March, 2017 – INTERXION HOLDING NV (NYSE:INXN), a leading European provider of carrier and cloud-neutral colocation data centre services, today unveiled DUB3, its third data centre in Dublin, and further strengthened the company’s commitment to its future in Ireland.The €28 million data centre which is located in Grange Castle Business Park was officially powered on by Tánaiste and Minister for Justice and Equality, Frances Fitzgerald TD. During the construction phase of the project 140 jobs were created, with 10 permanent new positions created following construction. This will rise to an additional 40 permanent positions when additional construction phases are complete. Speaking at the opening of DUB3, Tanya Duncan, Managing Director of Interxion Ireland said: “The data centre industry in Ireland continues to thrive and the Grange Castle Business Park has become a strategic location for businesses looking to interconnect mission critical services in Ireland. DUB3 was built in direct response to increased customer demand and new opportunities in the Irish market. A number of new technologies have emerged in the past few years that have re-positioned the value of a modern data centre. In the past a data centre was seen as a way to support business. However, in today’s world, business and technology have evolved to the extent that the data centre is the central connection hub for organisations of all sizes. The global connectivity that is now so central to all our lives is reliant on the data centre.“Since Interxion opened its first data centre in Ireland in 2001 demand for our services has continued to grow and evolve as Ireland’s economy changes. This growth has come from both new clients to Interxion and to the Irish market and also as a result of our current clients expanding their own businesses. Today’s opening demonstrates Interxion’s commitment to Ireland and is the result of the continued support of the Government and IDA Ireland.”Developed in response to continued customer demand, the new data centre will provide approximately 2,300 sqm of equipped space in four phases and total customer-available power of approximately 5MW. To ensure maximum energy efficiency, DUB3 has been designed with a focus on energy-saving, modular architecture, incorporating cooling, as well as, maximum efficiency components. DUB3 will provide access to 40+ carriers and ISPs, as well as INEX, the Irish internet exchange which has established PoPs in Interxion’s existing Dublin data centre campus.Speaking at the official opening, Tánaiste and Minister for Justice and Equality, Frances Fitzgerald TD said: “Over 200,000 jobs have been added to the economy since the launch of the Action Plan for jobs in February 2012. This demonstrates that the economic recovery is being fuelled by job creation from companies like Interxion. These new positions show the commitment of companies like Interxion to West Dublin and are a vote of confidence in the talent and skills available in the local areas of Lucan and Clondalkin. We have seen continued investment by companies such as Interxion here in Grange Castle Business Park, leading to this business park being one of Europe's leading hubs for industry. I wish Interxion and their team every success with their continued business in Ireland”.
