The move will see Interxion increase its 2014 annual capex guidance to between €175m and €200m.
The Frankfurt and Amsterdam expansions are part of its strategy to meet customer demand across its pan-European footprint.
“The strong bookings momentum that we experienced in the fourth quarter of 2013 has continued into 2014, as cloud infrastructure providers continue to commit resources to prepare for European enterprise cloud migration,” said David Ruberg, CEO at Interxion.
“Consistent with our strategy to prudently align investment with customer demand, we are accelerating and expanding construction of AMS 7 and FRA 8 in response to committed customer orders.”
In January this year, Asia's Global Transit has expanded its international presence with the launch of a PoP at Interxion’s data centre campus in London, UK.
