Why do all the links to CUDA 8.x refer to CUDA 9

I needed to get CUDA 8.x, but all the download links that I find on this site whether for CUDA 8 or CUDA 7 take me to the download for CUDA 9. How do I get to CUDA 8.0?

Presumably the links you clicked on point to the current CUDA version, so you get whatever version number “current” corresponds to at that time.
