When is the random election timeout is chosen?

[M Keyer]

Is the election timeout of a node chosen at the startup of a node and then used for the whole lifetime of the node (until it crashes or is shut down)? Or is a new election timeout also chosen during the lifetime of a node?

[John Ousterhout]

No, a new election timeout must be chosen for each election. This ensures that if multiple nodes happen to start elections at the same time and split the vote, they won't all pick the same timeout for the next election and conflict again.
