If it does have an effect, you might have to restart SM before you're
able to revisit the site.
I'd suggest a cache time of something closer to 5 or 10 minutes.
32767 seconds is a bit over 9 hours and the name -> IP address binding
is good for only 60 seconds:

Windows XP caches DNS responses ("ipconfig /displaydns" to see the
contents of cache), so additional caching in the browser that ignores
the name -> address time to live is just asking for problems.
