INTERXION HOLDING NV (NYSE:INXN), a leading European provider of cloud and carrier-neutral colocation data centre services, today announced that in response to continued customer demand it will expand in four cities: new data centres will be built in Amsterdam, Dublin and Copenhagen, and two expansion phases will be built in Frankfurt. When fully built, the three new data centres will have a maximum capacity of approximately 11,900 sqm. The additional capacity from the four city expansion is approximately 6,800 sqm and is scheduled to become operational in the second half of 2016.

“Interxion continues to experience solid demand for its highly connected and multi-cloud data centre capacity across key markets in Europe," said David Ruberg, Interxion’s Chief Executive Officer. “We continue to deploy capital to expand capacity in a disciplined manner in response to this demand. As a result, we are today announcing additional capacity in four markets in which there is strong demand for further platform roll outs by cloud providers, and early cloud adoption by enterprises and systems integrators.”

Interxion will expand its facilities in Frankfurt by constructing the final two phases of its FRA10 data centre (FRA10.3 and FRA10.4), each new phase of which will provide approximately 1,200 sqm of equipped space. On completion, FRA10 will have approximately 4,800 sqm of equipped space and access to approximately 10MW of customer-available power. FRA10.3 and FRA10.4 are both scheduled to become available in the fourth quarter of 2016. Previously announced phases, FRA10.1 and FRA10.2, are scheduled to become available in the first and second quarter of 2016, respectively. As previously announced, capital expenditure associated with the full build-out of FRA10 is expected to be approximately €92 million.

In Amsterdam, Interxion will build its eighth data centre (AMS8) which, when fully constructed, will provide approximately 8,000 sqm of equipped space and a total of approximately 15MW of customer-available power. The build will be done in six phases, each of which will provide approximately 1,300 sqm of equipped space. The first two phases are scheduled to open by the fourth quarter of 2016.

AMS8 will be located on Interxion’s Amsterdam campus at Schiphol Rijk, which currently provides access to more than 40 carriers and ISPs, as well as two Internet exchanges. The capital expenditure associated with the first two phases is expected to be approximately €50 million.

Interxion will build its third data centre in Dublin (DUB3). When fully constructed, DUB3 will provide a total of approximately 2,300 sqm of equipped space in four phases and total customer-available power of approximately 5MW. It will be built on property owned by Interxion and will provide access to nearly 40 carriers and ISPs, as well as the Irish Internet Exchange which is based at our existing Dublin campus. The first two phases of DUB3, which will provide a total of approximately 1,200 sqm of equipped space, are scheduled to open in the fourth quarter of 2016. Capital expenditure associated with the first two phases of DUB3 is expected to be approximately €28 million.

Interxion will build its second data centre in Copenhagen (CPH2). When fully constructed, CPH2 will provide a total of approximately 1,600 sqm of equipped space and a customer-power density of approximately 1.5kW per sqm. CPH2 will be built on land next to CPH1 that is owned by Interxion and it will provide access to more than 40 carriers and ISPs as well as the two Internet exchanges that are based in CPH1. The first phase of CPH2, of approximately 500 sqm, is scheduled to open in the third quarter of 2016. Capital expenditure associated with the first phase of CPH2 is expected to be approximately €4 million.

The anticipated capital spend in 2015 for these projects is included in the 2015 capital guidance previously provided by the Company.
