Problem with servers

I have been attempting to play halo 5 matchmaking since six this morning, and keep getting the message; having a problem with dedicated servers. Try again. I tried multiple times, with the same results. How does 343 not know or address this? They did well with the issue last night, giving us a heads up, and even texting me when it was fixed. And how is it possible that there is no way to contact 343? Is anyone else having these issues?

it’s down again?
