Not sure what the deal is, but we noticed in our WSUS email alerts that the Forefront Client Security update definitions were missing, the only ones we were getting on a daily basis are Windows Defender definition updates.
I also checked the Microsoft update catalog and that also just shows the last definition update from July 15 (KB977939 (Definition 1.201.1826.0)
I was not able to find any other references of why these are not getting pushed.
Is anyone else having similar issues?
