Lobby server down. Can't load profile

I can’t do anything but play solo campaign. There is a message that pops up saying the guardian servers are down. I have tried resetting my router and Xbox several times over the past couple of days to try fix this problem, unfortunately nothing has worked. Any help?

What’s your location?
