Even when you are putting a data center in the middle of nowhere there are factors to consider. Take this proposed data center in Canberra, Australia as an example. It was unsuitable due to the presence of Aboriginal artefacts, the land was too small, it low-lying under a flight path and it was too close to a highway.
When it comes to data center location its not just a matter of having the space - the environment also has to be conducive. But given that the data center may be in the middle of nowhere, remote access, management and control takes on even more relevance.
