During the evening on Saturday June 20, 2020 between 0300 to 0600 UTC,
the NANOG Tech Committee will preform an upgrade of the mailman software
and migration of archives. During this time, all mailing lists will be
unavailable, including the ability to make changes to your subscription
We expect this migration to be completed in three hours time or backed
NANOG is committed to the availability of its mailing lists as the best
direct member community access medium. Ongoing issues with
"backskatter" and other annoyances to posters on the list are mitigated
in newer versions of mailman. NANOG will be upgrading to the newest
stable mailman 2.1 and enabling VERP (Variable Envelope Return Path)
. This will make each message to each user unique, and enable
tracing bounces or other backskatter annoying emails. VERP will mean a
slightly increased load on the MTA (Postfix), however in testing this
was found to be a non issue.
Our other addition will be to the archives. Currently all archives are
split into 2011+, 1994-2011 and even older archives from the NSFNet back
to 1992. All these archives will be merged and added into mailman
archives. This will provide almost 30 years of archives in a single
place. Should anyone have postings before 1992 please let us know, we'd
like to capture them as well.
Archives to be merged
Our testing shows this merge and rebuilding the archives to take from
50-70 minutes and will be the majority of the outage time.
A MOP or Method of Procedure is in-place for this maintenance with clear
go/no-go steps and a back-out plan should we find any insurmountable
problems. An update will be posted to the NANOG mailing list once this
Any messages sent to the list during the maintenance will be queued and
retried once the mailman server comes back online. This may delay some
messages for a few hours, but no messages will be lost.
Any questions may be directed to geeks at nanog.org or on-list if of
interest to the community.
