Description

Shorter DS TTLs=> shorter Mean Time to Recovery

DS RRsets need to be rolled back or updated promptly
No 24-hour or more downtime after emergency DS updates
Note: Cached validated child RRsets keep their existing TTLs!
No expected impact on child zone query volume
We’re studying expected effect on parent (eTLD) zone query volumes
