Thank you.

I fully agree. As suggested in Warsaw, we will keep running the old visualisations until RIPE 69 in London and will present the WG with real usage numbers and a few suggestions on how to move forward for a discussion and decision by the community.

Yes and we are fully committed to implement what is proposed by the WG. Regardless of old TTM decommissioning timeline, we can always introduce a delay in the new DNSMON results. As a matter of fact, Robert has prepared an email explaining possible scenarios to kick off that discussion, we are just waiting to hear from the WG on the status of the timeline in order to be able to commit to implement any possible change to the new DNSMON.

All the best,
Kaveh.
