BTB Not working anymore :(

I was finding matches in like 2-3mins before the patch, but since the patch i can’t find anything in BTB :confused: and a lot of my friends having the same issue ! And the population seem so low, i keep getting into the same people each time, the only reason why i left Halo 3 was low population but if that game die within month what would it be in 2-3months?
