In the past few weeks Dirk Astrath and me upgraded some of our infrastructure systems to Debian Buster and implemented some performance improvements.
The old staff list and community email password reset pages have been replaced with a modern system that is now available at https://selfservice.cacert.org/.
The git code hosting system at https://git.cacert.org/ has been upgraded to Debian Buster too and has been switched from gitweb to cgit for the git web frontend for much better performance. The old gitweb URLs are automatically redirected to the new cgit URLs. This change has the positive side effect that you can now use git clone directly using the https-URLs of the git repositories.
In the background we added Puppet configuration management for the above mentioned systems and replaced the aged nrpe-based monitoring with Icinga 2 agents.
We setup a new community start page at https://community.cacert.org/ that leads you to resources that we think is relevant for our community members.
