This edition was no exception, though as the editor, Julian Dibbell, notes in his introduction, the essays are heavily weighted towards all things digital, despite his efforts to seek out writing on other technologies.
There are two articles that expressly deal with data centers: Douglas Fox's Thinking Machine (which I have commented on already), and Vanessa Grigoriadis' Do You Own Facebook? Or Does Facebook Own You?.
Ms. Grigoriadis touches on Facebook's server footprint, though she feels it pales in comparison to Microsoft's Quincy WA data center, for example. I'm not sure that is really accurate now that Facebook is commissioning their data center in Oregon, which has about the same load as Microsoft's center - about 40 MW.
In any event, if you're looking for a compendium of articles to keep you current across a variety of technologies, this series is an excellent place to start.
