Every node renews its lease once a minute instead of every 30 minutes, so the lease works as a heartbeat. x:ClusterNode reports a node Stale once it has gone three minutes without renewing (it used to take an hour), and Inactive after a day, as before. Taking over a lease still needs a full hour of silence. A node that is slow rather than gone never loses its id to another host, so snowflake ids stay unique. The admin dashboard's Cluster Health card counts these statuses.
