Hello!
Since a few weeks now, the https://webhint.io/scanner/ URL is returning 404:
C:\Users\XhmikosR\Desktop>curl -ILls https://webhint.io/scanner/ | findstr 404
HTTP/2 404
Is the page gone or is it a mistake? If it's gone, I guess it should be redirected, although, personally, I used it from time to time, but I'm sure there were probably reasons.
