Hi @MushyPotato - when you rent a pod on spot and it gets stopped (really, when a pod gets stopped for any reason) the GPUs in that machine are made available for other customers, and by the time you can start it again there may be fewer GPUs available.
Setting up a network volume will allow you to deploy to any GPU within that data center, so you will not be limited by whatever the GPU rental status in your specific machine is.
