If you zoom all the way in, it's blurry (I know, I waited for the tiles to load). There's no single-pixel detail. That means it's not really a 9-gigapixel image

If you zoom all the way in, it's blurry (I know, I waited for the tiles to load). There's no single-pixel detail. That means it's not really a 9-gigapixel image, you can easily reduce it by 2x2, and make it a 2.3-gigapixel images. Save space, bandwidth and time for everyone.
