This latest magazine is all about time. It took three years to find the images for the cover feature, some of which have not been published in more than three decades.

The relentless march of time could also mean the end of other photographs from the historic collection, as they risk being lost to history. We uncover this forgotten archive, and tell the story of how it came to be.

Plus:

• The world's largest data center
• The battle for Northern Virginia
• Dublin's data center dilemma
• Trouble in Soviet Florida
• And more!
