I don't think there's anything to be done on our end. It appears that MS has failed to publish today's updates where our WSUS servers can sync them. There's another thread on this where multiple people are seeing the same thing:
WSUS Server Not Finding Updates
We're running at Windows Server 2012 R2 WSUS server and it's worked fine for years. We're pointing it to Microsoft Update servers to find and download updates. Today, it's not finding available updates from Microsoft. I've confirmed there is plenty of space on the content volume, and it's able to to reach Microsoft Update servers. I've also confirmed there haven't been changes to the Products and Classifications we're synching.
Does anyone have any tips for troubleshooting further? I've attached the software distribution log from the host in hopes that it'll help. 95626-softwaredistribution-log.txt95644-softwaredistribution-log.txt
