Maybe for some of us the servers are down so I made this thread to try to avoid a lot of other threads saying the same.
Don’t worry the servers will be back in no time if you have any question with the servers down please post them here 
When did it start?
Good to know that I’m not the only one experiencing this problem. Eighty-five percent of the time I tried to get on yesterday, I got a message saying I needed to connect to the Xbox Live, but I was connected.
