[luau] no answers from roadrunner dns

[Bill Luoma]

I'm wondering about nameserver config.
Specifically, caching. It seems like my provider,
road runner, hardly does any. For example,
I repeatedly request the page news.google.com.
I imagine many other hawaii customers do the same
thing every day. Yet, this entry is not cached
in their dns. Is this efficient for them, a policy, an error or just rude?
Or do they have a caching name server I don't know about?

thanks, 
Bill
