We’ve just implemented a much requested feature, the ability to boot your VPS from a rescue cd.
The rescue environment is based on SystemRescueCD
The rescue mode is useful for things like resetting root passwords, doing filesystem checks and recovery, offline scanning for virusses, and copying files from your VPS to another location.
When booted into rescue mode your VPS is connected to the internet, so you can access it with ssh like you’re used to.
