@asun Jamf removed public access to those pages a few months ago. My understanding is that the non-public links to course materials are now provided to students with their class information, but you'd probably want to check with Jamf Training to be sure.

Ah that's a shame. I was just trying to look something up, but I'll have to go rummaging through my course notes then. Thanks!

Ya, as @sdagley said Jamf pulled them. I was sad when I found out because I still referenced the material myself from time to time and would point new admins to the Jamf 200/300 documentation for guidance. 

I forgot to add, if you still have the old link give the Internet Archive Wayback Machine a try: https://web.archive.org/

I gave that a try earlier but had little success unfortunately.

I'm sure a lot of people aside from the two of us do the same thing!
