Flapping

Flapping is when a monitored service rapidly alternates between up and down, producing a storm of conflicting alerts.

Flapping usually signals a borderline problem (an overloaded server, a flaky network path, or bot protection) rather than a clean outage. Good monitoring damps it with confirmation across locations and cooldown windows so you get one clear signal, not noise.
