Live is a mess for me too,
The Xbox Live error page on xbox.com is showing problems for more than a week now. I've asked some guys from my friend list, checked some forums and a lot of people have similar problems.
XBL marketplace here in Greece is down for more than a week, we can't download the free game with gold because apparently the marketplace is totally empty (yes I'm not kidding even bing gives no results back), we can't redeem any codes, apps are giving various errors and sometimes even matchmaking/party chat/friend list is not working properly. I contacted xbox support on twitter a few days ago but I got no answer other than "if it is a widespread problem tell your friends to contact us".
This is the state of the marketplace here from 25/7:
Thing is we don't have any official statement regarding these issues, was this caused by the Destiny beta? is it some kind of preparation for the Xbox One launch here? is there a timeline that this is expected to be fixed? we don't know a thing and nobody is doing anything at the moment.
