On a possibly related note, I am trying to download the "SVM DR" pack (from the internal network) and cannot get past the captcha. And I know I typed it right at least once out of the 6-7 times I tried. Reproduced both with MS Edge and Exploder.
I'm experiencing the same issues as the other posters. I started to experience this issue early last week. I have tried multiple browsers on different computers. One thing to note, when I try to login it takes me to https://login.netapp.com. This page looks different than the standard login screen at https://signin.netapp.com. Also, when I click the forgot password button link on the https://login.netapp.com it gives me an invalid DNS address as it's taking me to it.netapp.com. Looks like some links need to be updated.
I just checked and I'm still seeing the same thing. I get a 404 error when trying to download the file if I'm already logged into the support site. If I'm not logged into the support site it takes me to a login page and my credentials will not work on that page.
