Realms seem to be non-accessible as it says I need Authentification from Microsoft Services.

When I loaded onto Minecraft, I went over to realms. I noticed that the names didn't appear under the realm names. I then clicked on it and it said I needed Authentification from Microsoft Services. A few minutes, I tried signing into my account but it said Xbox live is down so i'm stuck here wondering what should. I then came here to let you guys other than anybody else, I will be informing Xbox about this too. Keep up the Good Work Guys!
