This weekend I was having dinner with friends and we came on the subject of YouTube and how many videos there are online at the moment. The numbers are huge. “Can you imagine the serverpark that YouTube and Google have?” my friend asked me. I knew they were big, but to be honest I didn’t have a real idea of what they looked like. But Eric Schmidt was right when he said “We can more or less know what you’re thinking about” because along comes a tweet from Fili, a Googler yes, can you believe that. He retweeted a video which was shot in 2009 but which gives a great view of how these datacenters look like.
