I see the prompt at the top (nice).
But when I click through:

I just upvoted this question after the same thing happened to me. I just logged into ServerFault for the first time in a long time to see the message "You have 1 new response." I click it, nothing. I click through the date-spans, nothing. Well, what is the response?
Is it too tasking on the database to request the x-most-recent responses to show on that page? Fortunately for me, I only have a few questions, so I can manually scrub through and find the newest response. But if I have 10 questions, 20 questions, or 50 questions, this scrub-time becomes very tiresome.
Visit the site more often, then?
I agree it's not optimal, but this is by design at the moment; if we don't limit the query dates, the queries will time out.
edit: This is now complete.
