I'm guessing DoD and the FAA were squabbling over a test the military wanted to run, and it didn't go up the chain fast enough to get resolved before testing was scheduled to begin.
Edit: Here's the actual notice from the FAA[1]. Note that it was issued at 0332 UTC, but the restrictions weren't scheduled to go into place until 0630 UTC. Either the FAA is clairvoyant, or Sean Duffy is lying.
