We track DNS disobeyers at Google, as we use it for load balancing (along
with many other large sites).
I'd be kind of surprised if any large/professional ISP disobeyed the TTL
that badly, because it would cause frequent problems reaching popular sites
like anything hosted on Google or Akamai. But randomizing the DNS request
isn't a bad idea.
