I am having problems with all the subdomains under my site, like "sub.site.com.br", "other.site.com.br".
The problem I am having is that sometimes I can reach them and sometimes not.
From some locations I can reach and from others not.
This is very wierd :/
Anyone can give me any advice ?
I would recommend using your favorite name server querying tool and querying the servers involved, the servers you use for name resoultion and other servers that have not cached information from you domain.
I use the "dig", however "nslookup" and the "host" commands could be used equally well.
I know nothing about Cpanel but the weirdness is probably because different nameservers have loaded (cached) different versions of your domain records.
Specifically look at the serial number in your SOA (statement of authority) record
now are "sub" and "other" actually separate delegated domains or just hostnames. (are you using www.sub.site.com.br,
etc?) If so, it's probably time to break out the cricket book. DNS and BIND

P.S. by "reach", do you mean you can "ping" it or can you download web pages? If ping works and not dowload, you are either reaching the wrong server or your webserver is not configured properly.
