Looks like the server is asleep since no one requested for a page recently. I'm constantly refreshing the page until I receive a response, just to prime it for my fellow HNers in case this reaches top of HN.
Are you still working on this? I fired up my spider on ultra aggressive retry mode because that will help the DNS get cached for people in my isp. (They have funky cache settings). This should help thee Ed time to first byte for fellow HN neighbors.
