Data Center Photos and more
One of my favorite sites for quality free images is pixelio.de. I have posted some of my data center and other photos there under the profile AVATAVA. The photos are of the US Wireless Louisville, Kentucky and the Columbus Ohio Data centers. The Louisville Data Center is no longer in existence and the Ohio data center is no longer part of US Wireless.
The web site is in German only- even if you don’t speak German you should still be able to figure out the photos. 
Over the next few weeks I will upload more photos to the site under the key word rechenzentrum. All the photos are free for commercial and private use (copyright retained) as long as they are not used in association with illegal or immoral activities.
