OnPrem http://mms.mongodb.com/help-hosted/current/ goes to a page entitiled "On Prem MongoDB Management Service – 1.1 Release"

http://mms.mongodb.com/help-hosted/current/ and http://mms.mongodb.com/help-hosted/master/ are going to a page entitled :

On Prem MongoDB Management Service – 1.1 Release.

I believe that the documentation itself may be correct.

The pdf links are broken for both these releases. They seem to be working for the older releases.
