whats wrong with the servers?

So Since launch day I did not have any problem but now when I go in matchmaking I see for like 5 sec the normal playlist but then after it switch to the default playlist and it tell mme that the server are down spartanops dont work and my rank is at 0 whats wrong I tried restarting my router/xbox and it dosnt work

I have the same problem on and off, i get the default halo servers, reducing me to rank 1, but still giving me xp at my normal rank (36) after the game.

i get put on the default playlists, like 1000 people on them, very strange
