Are these physical servers or VM's? I ask because some VM types can be frozen/shapshot/cloned or live replicated including memory contents as is done in some VPS providers for lawful requests. From the bare metal host anything can be accessed in a VM or container. Do they have a diagram of their physical setup?
[Edit] - Are there any Mullvad architects here that can help us avoid going down theoretical hypothetical rabbit holes and turtle stacks?
