Servers offline?

Halo reach, halo 3 and halo 5 (not sure about halo 4) Servers have been offline for 2 hours meaning every game is non-multiplayer (besides customs) If some one knows why this is happening please tell me?

Feel free to follow this topic for the time being until the issues is resolved:
