Dear RSSAC Caucus,

 On behalf of the RSSAC Caucus Metrics work party, please find the draft RSSAC Advisory on Metrics for the DNS Root Servers and Root Server System.

  The work party was formed in January 2019. It is led by Duane Wessels and Russ Mundy. After 12 months of deliberations through teleconferences,  workshops,  face to face meetings at ICANN and IETF, the draft final advisory is ready.

   Kindly review the document by 10 January 2020:

• for any proposed changes, please send to the caucus list identifying the page number, the original paragraph or sentence, and your proposed edit.
• We are also copy-editing the document. For any copy-edit changes, please email it to steve.sheng@icann.org.

   WP members, please pay attention to the first bullet in the introduction, as it has been revised today as a result of the teleconference.

Best

Steve
