Realm Hiccups

I pay monthly for a realm.  Lately (last couple of weeks) the realm keeps having hiccups.  At first it was just a bit of rubberbanding.  Now, it hiccups and erases all progress made in the realm for the last 2-30 minutes.  It is progressively worsening, and becoming an issue to the point I am about to cancel the subscription since it is difficult to mine/build/progress in the game when you don't know if what you are doing is suddenly going to disappear.  We have had items vanish, and builds disappear.  Please Help.
