Remember — (from their own article announcing these servers):

This doesn’t mean you can’t be logged. Running in RAM just means that any system level logging is transient and largely accidental. But if there were a need to specific logging, data could always be sent to a different node with disks. From Mullvad’s point of view, there is a reliability benefit to having diskless nodes. But from a privacy point of view, your access could still be logged, if required. But it would probably require more “active” monitoring than “passive”/accidental logging.
