Yeah...I know. Unfortunately, the domain was "mishandled" by our registrar, who imposed their own TTLs on our zone, THEN turned it back over to us with a 48HR TTL. Which is very bad.
I really appreciate all of your help, guys! á§

The generally accepted and scalable way to accomplish this is to advertise your freshness preferences using the SOA record of your domain.

Seems like the DNS protocol already addresses this issue with TTLs. The issue is that people sometimes regret the TTLs they chose (or their service provider chose for them). Any reason registrars commonly choose a 2 day TTL? Would they be just as well off with a 1 day TTL (my guess is that they would)? --Blake Hank Nussbacher wrote the following on 4/16/2014 11:32 AM:
