Thank you again for your feedback on the TTL document. The Caucus work working group (along with a few caucus members) met at IETF 93 today and finalized the document.
In the attached final document, a few changes are made:
1) recommendations are updated based on the additional feedback and work party discussions. The rationale is documented at the end of section 6.4.4.
2) added text to indicate that this is not an urgent problem to be fixed, and that the issue to be addressed within a
reasonable amount of time following an update of the necessary procedures documents and software testing.
3) additional text to indicate that a new RRSIG record covering
the DNSKEY RRset appears in the root zone every ten days, except at the end of
calendar quarters where the interval may be extended to 12 days.
4) light-editing through the document (e.g. make recommendations in the executive summary consistent with the recommendations section, etc.)
5) updated acknowledgement section.
With this, this document is put to the 48 hour last call for comments period. Please provide your comments by close of business Thursday, 23 July 2015. Following the last call, the documents will be copy-edited and sent to RSSAC for formal action.
