The weirdest thing is that it's not a network problem. I tried using my brothers gamertag on the same Xbox and got online instantly, my account just won't connect for some reason. :S
Yeah it's very unstable today. In one game I was kicked out of the game and had to go back to singleplayer and then in the very next game I was logged out of Xbox Live.
Anyone else having trouble connecting? Every time I try to play online I have to wait 5 minutes, then it says "Timed out locating session."
Selecting online whilst the game boots up rather than in the game itself seems to get it stuck loading indefinitely with no way to stop it without quitting to the dashboard.
A few of the games I managed to join only had 2-3 players too and in a couple I was on my own. If it carries on running like this, the stimulus package will be released in a couple of...months.
