Knowing the size of a video file is exactly not the information, that would help me put this number in a meaningful perspective with any comparable operation.
How do I think of 42 petabytes in terms of an ISP? Is that a lot? How does it compare to other satellite providers? How does it compare to 4G capacities? Is this a small country worth of traffic or just any ol' data center? I have no intuition about traffic at this scale.
