# FAQ

**Where do VMs run?** DigitalOcean infrastructure across four regions (New York, London, Amsterdam, Singapore).

**Are stopped VMs billed?** Yes. Stopped VMs reserve cloud resources and bill at full rate. [Suspend](/platform/vm-management#suspend-vs-stop-vs-destroy) to pay only image storage, or destroy to stop billing entirely.

**What if I run out of credits?** Running machines are snapshotted and destroyed. Snapshots are retained -- top up and recreate. Enable [auto-topup](/introduction/pricing#wallet) to prevent this.

**What tools are pre-installed?** The `ubuntu-24-04-loaded` image includes Docker, Node.js, Python, Go, Rust, Bun, Claude Code, Codex, OpenCode, tmux, zoxide, fzf, ripgrep, and bat. See [Images](/platform/images).

**Can I export my data?** Yes. SSH in and copy anything, or use `machine0 sync pull`. With NixOS, your OS config is portable to any NixOS host.

**Can I use my own SSH key?** Yes, that's the default. The CLI registers your `~/.ssh/id_rsa.pub` on first use. See [SSH](/platform/ssh).
