Hi all, Corinne (cc) and I are doing some qualitative and quantitative analysis of IETF and IRTF mailinglists (partially using BigBang [0]). While doing this we found out that there are some discrepancies between different mailinglist archives. For instance compare these two: https://ietf.org/mail-archive/text/hrpc/ https://mailarchive.ietf.org/arch/browse/hrpc/?so=date# One start in April 2015, and the other starts in October 2014. This can be attributed to a mailinglist migration, but it begs the question which archive is authoritative, and why are there two different archives? Another related question is whether there is a list or mailinglists that are used for RGs and WGs that are not being hosted here: https://ietf.org/mail-archive/text Looking forward to hear from you.
