It's nice to receive a notification telling us that a service is ending, though it's not nice to know that a service is ending. Somehow, it is better than you find that the page is missing after a few months.
I remember when some of my friends started a Malaysian map service. They sent me an notification, asking me to join. However, after a few months, when I tried to look at the service, the domain name is no longer available. At this point, you really don't know what actually happened to the service and how they are going to use your information.
Just imagine, one day when you open your Gmail account, the website is missing. The service is gone, just like that. Your emails are gone, just like that.
Recently, I received more than one notifications from Ringo, a friend-networking website last time (I don't know when it switched to be a photo and video sharing site), which I suppose to be taken down due to the rise of MySpace or probably Facebook. Or for its new business, Flickr or Youtube. Or probably it's taken down simply because it is not 2.0 enough.
Anyway, it's certainly a good thing to do, to inform your users that you will stop your service and more importantly, ask your users to backup whatever information they have with you. What Ringo did was good, they provide alternative way to get their pictures and videos, which is allowing their users to get their data through CD.
