I believe that any posts and comments that were pulled and stored on your server will remain but new posts or comments will no longer federate. I'm actually not sure if new posts would be possible at all but you could always test it by setting up 2 servers.

I've been wondering the same thing. Hopefully someone knows a solution.
The future of the Internet looks strangely familiar... almost like the email servers of yesteryear.
