Randomly when I start up my xbox and try to play a game on xbox live, it will say that the game's server is currently unavailable, but my friends will be playing so it cant be a problem with the server. Also randomly, i won't be able to connect to my friends' xbox live parties, or marketplace content will be unavailable, or indie games won't work, or if i do manage to search for a match in a game on xbox live, it won't ever find a game. It hasn't done this until just recently and i don't know of anything that has changed with my internet connection to cause this. My nat type is open, and i dont recieve any error messages, i have gone through all the standard troubleshooting, but to no avail. Can anybody help me out?
