Dear Liman Thanks you for hosting Caucus meeting. I really enjoy the communication with every members this afternoon. Here I just want to send you formally the suggestions I raised in brainstorm session. 1) draft report on expectation and measurement of root servers from customers side RSSAC 001 and 002 focus on the expectation and measurement of root servers from root operators side. But considering DNS resolution mechanism, the one-way measurement from root operators would not be able to reflect root service seen on the stub-resolvers or recursive servers. During the root mirror instances deployment in China, we found the end user side measurement is vital for root service evaluation and planning. We suggest that expectation and measurement from customer side should be considered, like what ICANN test New gTLD. 2) involve more parties in root operation At least for emergency response and communication, local root mirror hosts should be informed and could provide assistance. Some recursive operators should also be considered if they load zonefile in cache as described in draft-ietf-dnsop-root-loopback-01. Hope these suggestion might help. Btw, I just quit from CNNIC, could you please replace wangwei@cnnic.cn into wesley@zdns.cn in the mailing list? thanks Regards Wang Wei
