Yesterday, a massive server problem prevented players from going online to play Battlefield 1. This error was curious, as it only occurred on the Xbox One, and though Microsoft was fixing problems in regards to servers, it was for other games, not Battlefield 1. In fact, the players themselves had to show Microsoft the errors in order to get their attention to make the fix. However, they did fix the issue, whatever it was, and players now have access to the servers. Microsoft has not made known what caused the problems in the first place.
Yes, i have noticed it while I was trying to playing. It was much annoying. I face it for other games too but after some time, it was solved. They would never tell the exact reason because of their policies but I am happy that they solved it.
