I get this message when I go to war games stating
“The Halo 4 servers are not available.
Please try again later.
Matchmaking has switched to using the default playlist.”
Also here is the players active on each playlist
Infinity Slayer: 174
Big Team Infinity Slayer: 73
Regicide: 18
Capture The Flag: 7
King Of The Hill: 3
Team Slayer Pro: 2
I cannot join anyone. Nor can anyone join me. Help?
Bump:3 this needs to be seen
It’s a problem on their end.
I’m in the same boat for about 2 days maybe more. Angers me that I can’t play.
343 says wait 10 minutes.
Or
Dashboard
Or
Restart Xbox.
None of this works for me. And a few hundred others maybe thousands during busy hours. We are all on different hoppers.
At least I know im not the only one. I had a team Scrim scheduled and GB’s for later ):
It’s a cross you fingers and hope it fixes itself. 343 has not officially stated anything more than what I said.
This has been an issue for me since last night. Really bummed cause I was excited to play spartan ops episode 3. I thought 343 would have fixed this by now.
servers been down for 13 + hours for me now. crazy thing is is it’s working for my son and the guys I work with and my son lives in the same house as me. talk about frustrating!!!
You’re not the only one.

What!!! 343 are still having server issues… how. All the players have left, the servers can’t possibly be struggling to host 50,000 people can they?
same here it says exact same thing and I cant play spartan ops and my rank says im SR1 not SR59! This is unacceptable to 343, really shouldnt be that hard to set up the servers for only 50,000 +, but now it only says 169 people online now… whats going on??? it started yesterday for me now almost 2 days exactly now. this really makes me just play a different multiplayer game now. I guess I just stick with the campaign for this game now on…
