Abstract:
   This draft defines a method for recursive resolvers to use stale DNS
   data to avoid outages when authoritative nameservers cannot be
   reached to refresh expired data.  It updates the definition of TTL
   from [RFC1034] and [RFC1035] to make it clear that data can be kept
   in the cache beyond the TTL expiry and used for responses when a
   refreshed answer is not readily available.
