Here is a statement by the director Timo Arnall:

In this film I wanted to look beyond the childish myth of ‘the cloud’, to investigate what the infrastructures of the internet actually look like. It felt important to be able to see and hear the energy that goes into powering these machines, and the associated systems for securing, cooling and maintaining them.

Here is the trailer for the film, which is currently being screened in Barcelona at Big Bang Data:

The star of this movie is a very large data-center in Alcalá, Spain. Its servers, corridors, concrete walls, backup generators, pipes, wires, vents, coolers, water towers, and constant humming—this is the hard matter through which flows and flickers our growing information, our images of the deepest parts of space and time, our images of porn stars in India, our micro-posts about the passenger plane that vanished in the air over an ocean. "How, then, can I translate into words the limitless Aleph?" This is Borges in the short story "Aleph." But his Aleph (its infinity of images), like our clouds, has a hard place in the real world.
