Why do you have to control your own fiber to connect the data centers?
One of the neat things about the bubble is that people built all of this fiber that is now essentially free. What’s funny about our fiber leasing and purchasing is that people are always assuming that we have some master plan involving telecommunications when, in fact, if you think about it as just solving the supercomputer problem, we just want the thing to be faster.
