Error
Please add a CNAME record with the value/target xxx.cloudnexus.cc to your custom hostname. If you have already added the record, please allow up to 48 hours for the record to propagate
根域名cname可能會出問題,正常來説根域名是不能cname的,CF自己有一套方案處理這個問題讓他實現正常解析,但是用到cdn上估計會有問題。

As a result, the DNS spec enshrined that the root record -- the naked domain without any subdomain -- could not be a CNAME.
