This means that it's online but that the web server is down.  Ping just
tests physical connectivity, that is, if a machine is connected to a
network.  The 80 refers to port 80.  That's the standard port for a web
server to use to listen for connections.  

For example, you can ping www.google.com, you can browse it in a web
browser or telnet to it on port 80.  However, you can't just ftp
google.com and get an ftp server, because they aren't running one for
the public.
