Random Rollbacks

Over the past couple of hours, i keep getting D/ced for no reason. When i log back in, I find my character rolled back about 10-20 minutes. Generally I just have to turn in a quest again, so it isn't that big of a deal, but it is starting to get really annoying. So far it has happened twice to each of my characters online (3 characters on 3 computers) while in the mushroom kingdom. I don't have any good screenshots, but next time it happens ill try to get one.

Edit-
now it won't let me in to demethos at all XD. Maybe its just a demethos problem?
