Our site is connected through the Shaw Cable.
I trusted Shaw Cable periodically change the IP address assigned to their clients. Normally it is one year.
The IP address of server was changed on December 5 noon. I changed DNS settings accordantly. The DNS settings need about 24 hours to 72 hours to synchroniz the settings to all aroung the world ( Internet world ).

It is 9:49PM pacific time Dec. 7, 2005. Part of the world can get this site correctly. The remains are still resolved the old ip address and show the error message.
I hope after next 24 hours the domain name can be resolved correctly in the whole world.
