No, Asterisk (like many other pieces of software) is not very good in  
handling DNS failures. If you have a local caching DNS server on the  
same server, this wouldn't happen.

At some point we need support for asynchronus DNS, meaning that  
Asterisk would time out and not hang when there's a lack of answer on  
DNS requests.
