Interxion To Build New Data Centre In Madrid

23 May 2012

Expansion in Response to Customer Demand for High Power Data Centre Services

AMSTERDAM, 23 May 2012 – INTERXION HOLDING NV (NYSE: INXN), a leading European provider of premium carrier-neutral colocation data centre services, today announced that, in response to growing demand from its customers, the Company is building its second data centre in Madrid (MAD2).

MAD2 will be constructed in two phases, each phase providing 800 square metres of equipped space and over 1.2 MW of customer power.  The first phase is expected to become operational in the first quarter of 2013.

The MAD2 data centre is adjacent to Interxion’s MAD1 data centre in the heart of Madrid’s "Silicon Alley" and will offer customers the same rich connectivity options as MAD1, which houses over 70 carriers, the broadest connectivity in Spain. 
“This new build is in response to a strong and growing pipeline of demand in the Madrid metropolitan area from high power application providers, including cloud services, digital media, and other connectivity driven IT services,” said David Ruberg, Interxion’s Chief Executive Officer.  “As the Spanish market leader and the only pan-European carrier neutral data centre operator in the country, Interxion is ideally placed to meet this demand.”

The new data centre is secured by a long term lease and is designed to offer up to 1.5 kVA per sqm of continuous customer load, all of which has been secured.  The capital expenditures for phase 1 of MAD2 are expected to total approximately €10 million at full capacity and full power. The Company's 2012 CAPEX guidance of €170 to €190 million includes the forecasted 2012 spending for the MAD2 facility and the power expansion.
