Here's what I've got
domainabc.com         IN   A   123.12.3.4
www                            IN   A   123.12.3.4
mail                             IN   A    123.12.3.4
apps                            IN   A     123.12.3.4

I changed all the records from CNAME to A.

As you can see, they all point to the same machine. I'm not sure if this 
syntax is "legal" or not.

I asked a friend who lives in the country where the server is co-located 
and he can get very fast response. I have checked on the access log, and 
this fast response is corroborated. But it is strange that in Singapore, 
where I live, the response is terribly slow!!

The application, which does not belong to me, does a re-direct. Not sure 
why it has to do that either.
