I'm sure this is just a coincidence, but they're shutting down our Microsoft platforms on the NIPR and SIPR* nets this evening for an emergency patch.
Just a coincidence, I'm sure.
Everything is fine.
Nothing to worry about.
* SIPR - Secure Internet Protocol Routing, used for classified traffic. NIPR is Non-Secure. Pronounced "sipper" and "nipper," if you want to sound like one of the cool kids.
