Glad I did read this post. Just add the .htaccess to my uploads folder and will get to the other security upgrades in a few hours.
Maybe Dreamhost could alert it's customers about this in a more urgent direct way.
I of course did not read the NewsLetter and almost never check the Dreamhost status since all always works fine on my sites/server (hope I did not jinx it now)
Anyway, something as important as this and the other security improvements (THANKS FOR THAT !!!), could maybe get a single email to all customers, with a catching headline: IMPORTANT, Add new security Features
Anyway thanks guys.
PS. Of course we are all ourselves responsible for our sites, but most people need a big kick under their .... to get moving or even read.[hr]
