Servers Down or Offline?

Is the Halo: Reach servers down or are they back online?
I had this issue yesterday while playing with some friends. It kept on dissconnecting and lagging. And one of my friends said that the servers were down.
Is that the issue or can it be something else?

its because the servers aren’t supported any longer resulting in this experience

The servers run fine, it’s just the players. Although the servers are checked routinely, they’re still manageable.
