When accessing https://the-eye.eu/public/AI/pile_preliminary_components/, a 404 error occurs

Thank you for your contribution. 
I was trying to access the source data of GitHub, but suddenly https://the-eye.eu/public/AI/pile_preliminary_components/ is no longer accessible. 
A few days ago, I was able to access this URL. 
Could you please let me know what happened? Has this website been discontinued?
