Hello List,

We use SRV records extensively (for internal service discovery, etc.).

When the patch was integrated to support a 0 weighted SRV records, I thought 
that would simplify our setup, because at the time, I thought 0 weight meant 
"backup server" without a "backup" flag on the server. Unfortunately for our 
simplicity, that is not the case. A 0 weight means "will never be used unless 
explicitly chosen".

That leads me to my questions:

- Is that the intended behaviors of 0 weight servers: to not function as a 
backup if all other servers are down?
- Would you (Willy?) accept a patch that used the Priority field of SRV records 
to determine backup/non-backup status? Or perhaps an additional server option 
to specify 0 weighted SRV records means "backup"?

Best,
Luke
