percentage of jessie systems left as of today (because we were asked): 4.2%

I have proposed to do the final steps for decommission of old backups servers heze and helium in FY2021Q3. T260717 (CC @akosiaris @MoritzMuehlenhoff - I don't think I will require anything specific from you except maybe the occasional review to cleanup old puppet code, but giving advance heads up in case it helps).

the occasional review to cleanup old puppet code

there is only https://gerrit.wikimedia.org/r/c/operations/puppet/+/626460/ DHCP and an entry check-microcode.py: blacklist_mds = ['helium']. That's it.

I have started the decommissioning process oh helium and heze and marked the tracking tasks on the description. It may take a bit to process them as we need to do lots of cleanup (beyond the previously proposed patch), but work has started.

helium and heze are now in hands of the respective dc-ops owners (tracked on the tickets on the description) and software-wise (puppet/traffic), removed from our production.

the occasional review to cleanup old puppet code

there is only https://gerrit.wikimedia.org/r/c/operations/puppet/+/626460/ DHCP and an entry check-microcode.py: blacklist_mds = ['helium']. That's it.

All of this was done at: https://gerrit.wikimedia.org/r/c/operations/puppet/+/658969

Revert of "Downgrade to TLSv1 for backup" is now tracked at T273182, only conf2* (jessie) hosts are relevant for that.
