That's not the problem.  It's ill-behaved clients that ignore TTL
and query every 10s no matter what.  See some of James Smith's
posts...

If somebody wants to chew their own bandwidth and server
resources and add latency, that's their business.

At the other extreme, we have large providers that ignore TTLs
and refuse to refresh more than once a week no matter what.
