Currently, I am rearranging all the source codes in most of the site under the buss.hk domain. I've tried to use a masked domain name which map different sub-domain to a single server. Since, it need time to distribute the DNS information, some of my websites seems to be not working and white screen for a long time.
It's the time for reviewing the DNS strategy. I think I would rather map a masked domain to a dynamic domain using CNAME. Then, the response of the DNS should become faster and I should , in the future, avoid adding subdomains directly in the DNS server.
Bye for now, happy programming,
