Sorry about the lack of updates since I rolled in from O'Hare at 11:55 PM on Friday. Comcast gave our cable modem a new IP number on Thursday which caused HongPong.com to get disconnected.
It should be working now, but it's a very annoying problem. Comcast has rather pokey DNS servers, so even when I fix my number, it still takes them forever to update their system. Right now I am using the University of Minnesota's fine Domain Name Server at IP 128.101.101.101 to get at my own damn site!
If you ever want to use a different DNS server than your Internet Service Provider's, go to your network control panel or network system preferences and set "DNS server" to 128.101.101.101. Dang nabbit!
