Does Amazon Route 53 have a minimum TTL?

CodePudding user response：

I'm able to set a record to a one second TTL.

The interface states:

Recommended values: 60 to 172800 (two days)

but no limits appear to be enforced; that said, remember that Route53 incurs a small per-query cost, so a very low TTL on a frequently requested record may wind up getting pricey.
