Server Maintenance

Is there server maintenance going on right now or is the game just down? Also, is there a place where 343 notifies people of such issues/planned maintenance? It seems to happen randomly without any notice or acknowledgement.

There is an issue with Halo services right now that is affecting Halo 5, MCC and Halo Wars 2. 343 are aware and are investigating.
Maintenance is generally announced in blog posts here on Waypoint and on the Halo Support twitter account:

Thank you for the Twitter link, I was unaware of it!
