European colocation heavyweight Interxion reported healthy financial results for the year’s first quarter, despite Europe’s economic weakness.

The company’s CEO David Ruberg said the quarter’s uptick in regular sustained cash-flow and new clients demonstrated the data center market’s strength against the generally poor economic climate in the region.

“Recurring revenue increased by more than 4% over the quarter ended December 31, 2011, and strong bookings in the quarter reflect a continued healthy market for our services, despite sustained economic weakness in Europe,” Ruberg said.

During the quarter, Interxion opened its seventh data center in Frankfurt. Including the brand new facility in Germany, the company added about 21,500 sq ft of live data center space total over the three-month period.

Interxion reported €65.8m in revenue for the quarter – a 14% increase year over year. As of the end of the quarter its recurring revenue was at €62.3m – a 15% increase year over year.

The company’s net profit was €8.7m – up 210% from the first quarter of 2011. This translated into €0.13 earnings per share.

As of the end of the first quarter, Interxion had about 700,000 sq ft of space online across Europe. About 70% of this space was occupied.

Today, Interxion has 29 data centers in 11 European countries. The facilities have access to more than 400 network carriers and internet service providers and are connected to 19 European internet exchanges.
