LONDON – 24 April 2012 – INTERXION HOLDING NV (NYSE: INXN), a leading European provider of carrier-neutral colocation data centre services, today announced that BATS Chi-X Europe is providing an access point at Interxion’s City of London data centre to facilitate capital market participants to connect to Europe’s leading liquidity venue’s primary and secondary sites.

The access point at Interxion reduces the costs and complexity of connectivity to BATS Europe for market participants located at the Interxion data centre and may offer advantages to those market participants located elsewhere in the City of London. In addition, the site offers a great location for disaster recovery (DR) purposes. Market participants located at Interxion can cross-connect to the access point, allowing them to route their orders to the BATS Chi-X Europe and pick up the market data feeds.

Paul O’Donnell, chief operating officer at BATS Chi-X Europe, commented, “We’re committed to increasing value to BATS Chi-X Europe trading participants and providing them the ability to choose the connectivity option that best suits their needs. Our decision to open an access point at Interxion’s City of London data centre is based on its central location and accessibility to a large number of market participants.”

Greg McCulloch, UK Managing Director at Interxion, added, “We’re delighted to announce the opening of the access point to BATS Chi-X Europe at Interxion. The fact that they have chosen Interxion further reflects our position as a leading provider of colocation and proximity hosting services to the capital markets industry. Market participants can now benefit from easy, cost-effective access to this leading European liquidity venue from our City of London data centre.
