The Arch Archive has been cleaned up, the discussion started in this mail thread. The archive server was running out of space and therefore needed some cleaning, all packages which are not required for reproducible builds where removed (and where from 2013/2014/2015). Packages from these years should also be available at the internet archive.
There will be an Arch Linux Devroom on the Sunday of FrOSCon with talks and the possibility to meet members of the team.

A proposal has been send out to remove 'orphan' python2 modules. As a start of phasing out python2 packages.
