Hey everyone,

We have resurrected our draft Improving DNS Service Availability by Using Long TTL Values, and added some new polish to it.  We've taken some feedback from various people and would love to hear any thoughts other people have.

Thanks!

Eric

>   Due to the hierarchical tree structure of the Domain Name System
>   [RFC1034][RFC1035], losing all of the authoritative servers that
>   serve a zone can disrupt services to not only that zone but all of
>   its descendants.  This problem is particularly severe if all the
>   authoritative servers of the root zone, or of a top level domain's
