Unless you've worked at Amazon, Microsoft, Google, and Facebook, or a whole bunch of datacenter providers, I'm not sure how you could make that claim. They don't really share that information freely, even in their stock reports.
Heck I worked at Amazon and even then I couldn't tell you the total datacenter space, they don't even share it internally.
