> from the docs.
The load balancer must be configured to take a maximum of 30 seconds from the
time the API server turns off the /readyz endpoint to the removal of the API
server instance from the pool. Within the time frame after /readyz returns an

every 5 or 10 seconds, with two successful requests to become healthy and three
to become unhealthy, are well-tested values.
