Dear RSSAC Caucus Members, The RSSAC Caucus will be meeting at IETF 126 in Vienna on July 19, 2026. The RSSAC Admin Committee is requesting submissions for lightning talk presentations for this meeting. Proposed presentations should be relevant to the work of the RSSAC Caucus or at least root server system adjacent. All DNS related topics are welcome, but we are particularly interested in anything related to the root server system, root server operations, measurement, security, etc. Presentations can be given in person in Vienna or online. It is not required for participants to register for the IETF meeting, but it is required to have an IETF Datatracker account. Please send any proposals for presentations to me and Daniel Gluck before July 3. If you can send slides with the proposal we prefer them either in PDF or google slides format. But even if you just have a proposal with no slides yet send us a mail and we will discuss it with you and the RSSAC Admin Committee. We're doing rolling submissions this time, first come first served. If we run out of presentation slots I will let the Caucus know. July 3 -- Cutoff Date for submissions July 19 -- RSSAC Caucus Meeting in Vienna Thanks, Andrew & Dan
