I work with computers for a living, and I’ve been in a lot of computer rooms from closets to massive structures that support multinational companies.  Some facilities have been shabby, others well appointed.  This video by Computerphile gives a fantastic walk through of a functioning data center.

From the video description:

Inside one of the mysterious buildings that holds petabytes of data and crunches big numbers. Spencer Lamb shows us around a purpose built data centre in Slough in the UK, used by an organisation called Jisc/Janet which helps connect academic institutions together.
