Realm suddenly disconnects everyone and reverts to older save.

Hello this evening 27/01/20121 from 23.00 p.m. (+1 GMT Amsterdam, Berlin, Rome), if I log in with my account in the realms, the server after 1/2 minutes disconnects all players, console, pc, tablet. I play with an Xbox One S. Strangely, if I don't log into the realms, other players continue to play without problems.
