"The Halo servers are not available blah blah

My brother is connecting fine at his house and so is a mate of mine. It says I’m currently using the back up servers instead of the proper ones. First time I’ve had this problem.

And no, there’s nothing wrong with my 30mb fibre optic broadband.

Now I can’t get into a game at all. It’s just searching endlessly for the other 237 players apparently “online” in Slayer.

NAT open btw.

What is this nonsense?
