[dnswl-users] Query rate limit

[Mike Cardwell <dnswl-users@xxxxxxxxxxxxxxxxxx>]

Hi,

What is a reasonable number of lookups to be performing against the dns 
servers before it becomes desirable to start using the rsync feed? From 
the perspective of the people running the service I mean, not those 
using it...
Also, I'm trying to get a feel for the size of operation this is... 
Looking at the yearly graph on 
http://www.dnswl.org/mrtg/dnswl.combined.html I can see that the list 
didn't really start to take off in usage until a few months ago. Is 
there an explanation for this sudden increase? Are there any large users 
such as ISPs or Universities that can be named?
Regards,
Mike
