Diners is a franchise system. It may be that the current agreement is expiring and that Diners Club International has awarded the franchise to a different company, or that Discover intends to operate it directly, but it seems unusual that they did not announce their plans if this is a transition.
It is very unsual, I know. I have been DC member for many years although I dont use it, but I will miss it.

Try to call DC France, Holland, Belgium or luxembourg if you want to confirm what I said. Use Skype, it is cheaper.
