`DEAD` servers will show up in the yb-tserver list in yb-master as an artifact of the cached state in the current yb-master leader's memory. This cache is cleared after 24 hours. The quickest way to refresh this is to elect a new yb-master leader.
The `yb-admin` cli provides us a subroutine to do exactly that with [`master_leader_stepdown`](../../admin/yb-admin/#master-leader-stepdown).
