[OPS-DIR]Re: Opsdir telechat review of draft-ietf-dnsop-must-not-sha1-06

[[e-mail]]

Hi Thomas, 

Thank you for your first opsdir review. Welcome!

FWIW, I balloted "DISCUSS" as I have some blocking points to resolve first: https://mailarchive.ietf.org/arch/msg/dnsop/eUM1DT_ttH6dy4VAvS7sf17OYKg/.

Cheers,
Med
