momjian.us is down?

I am trying to connect to http://momjian.us/ but I get connection 
timeout (from Firefox):

The connection has timed out

The server at momjian.us is taking too long to respond.

     The site could be temporarily unavailable or too busy. Try again in 
a few moments.
     If you are unable to load any pages, check your computer’s network 
connection.
     If your computer or network is protected by a firewall or proxy, 
make sure that Firefox is permitted to access the Web.

Same from curl:

$ curl http://momjian.us/
curl: (7) Failed to connect to momjian.us port 80: Connection timed out
