Datacenter IJsselstein


Hogebiezendijk 21
3401 RS


The Gerbrandy Tower may well be the best-known radio mast in the Netherlands and it is most certainly the highest (372 m). This tower, including the antenna, is higher than the Eiffel Tower. For years, the tower was known as the tower of Lopik, but because of municipal reorganisation, the tower is currently located on the territory of the municipality of IJsselstein.

The radio mast has an interesting history. Maarten van Rossem filmed a documentary for RTV Utrecht and scaled the tower, which is no mean feat for someone with a fear of heights. The mast is decorated with lights on the tethers (almost) every year around Christmas time, resulting in an extremely large ‘Christmas tree’.

The datacenter set up in the tower has the largest capacity of all our datacenters: over 1200 kVA. It is not the largest in terms of surface area, though; that would be the datacenter in Roermond.
