Hi Betsy, Cloudflare DNS hangs out in the dns- oarc community. You can reach out here: <https://chat.dns-oarc.net>. You can self\- subscribe to our Community chat there. All DNS All Day long. Also, we operate the [email protected], and several other lists and initiatives that are operational DNS focused. Feel free to reach out with questions. I will be at NANOG in Bellevue in a few months too if you are attending.
