Halo 4 is down?

Can anyone play MM atm. It’s coming up with that error message saying I am not connected to Xbox live. It’s not just me too. It’s everyone on my friends list. Is it a Microsoft problem or is 343 have trouble running a game? Because I am pretty sure that there isn’t an update.

I’ve had the same issue. Looks like it’s a Live issue. Go to Xbox Support to see more.

I’m able to get on now though
