=== A Word on NiceCity ===
So the machine is back online and works fine. Supervision is working too though it still need some tweaking.
The work to rebuild the backup is in the todolist now.
=== System Upgrades ===
We've been preparing upgrades to Debian Buster and the work has already started. Nicecity was rebuilt on Buster directly. Elwing recently migrated too, so we were able to adapt our deployment rules. Not everything is ready for all machines to migrate yet but we're going to start migrating machines starting from now. Because of kernel changes and also some network settings that needs to be adapted, this means at least one reboot, maybe more. We'll try to minimize downtime but expect some short disruptions. You can follow the steps on IRC.
