NixOS CI/CD server ("Hydra") maintenance

Scheduled for May 7, 21:00 - 21:30 CEST

Scheduled

Security releases for Nix and for the Linux kernel have been published which affect our NixOS platform CI/CD server ("Hydra") that generates our Linux distribution and provides Nix channel tarballs. There will be at least one downtime of 10 minutes in this period while we apply updates, which can affect system rebuilds ("fc-manage"). Deployments might fail because of this.

The performance of running applications is not affected and package downloads are handled by our S3 object storage independently of Hydra.
