Recently, the Defense Acquisition University (DAU) changed its domain from a .mil to a .edu. When going to a DAU link from the APM you might have seen the following message talking about automatic redirections.
To our understanding, these automatic redirections will stop functioning on 20 September 2019. If we hear of a definitive date, we will update this article. Lastly, the APM has already been updated for all DAU links to use the .edu domain. This article is for your situational awareness.
