I update the site about once a month or so, mostly depending on the schedule 
for ARG meetings and the like. I try to crawl it every couple of months, 
updating the search indexes for the site:
http://www.ada-auth.org/search.html
and there are also separate searches for each set of AIs. For instance, the 
Ada 2005 AIs can be searched using:
http://www.ada-auth.org/search-ai05s.html

The changes themselves occur almost every day on my local machine, but I 
don't usually copy them to the server immediately.
