Scheduled - A Nix security release was published that affects 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 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.
