Which one was that? (Thing seem to be working for me.)

Works for me, and it's just a static page served up by nginx.

Could it be your browser is trying to use IPv6? The only scenario I can think of is that I messed up the IPv6 DNS settings (which I couldn't test from home).

Switching wireless networks fixed the problem. Thanks! And sorry for the spam.

It was an IPv6 thing -- I had configured DNS properly but nginx wasn't listening on that interface. All my sites should now be IPv6-reachable.
