It has been having quite the issues lately, I know my son has been a little upset, as his 360 barely had any issues. Considering he is 12, it could just be it seems to him it is always having issues. I do know in the last couple weeks it has been down 4 or 5 times for him.
Other than that, I do not really know how much it has been down. I do not have one myself, it is his X1.
