The ICMP monitor has been assigned to all nodes. In addition, all pools have been assigned custom monitors. If a pool .eb.is marked .vailable (green) which situation is sufficient to cause this.

All nodes responding to the ICMP node monitor does not guarantee the pool is Available, because pool member availability is governed by the custom pool-level monitor - members can be marked Offline by a failing content check even when the ICMP node monitor passes.

Less than 50% of nodes responding to ICMP means the majority of nodes are down, which would cause most pool members to be marked Offline and would likely take the pool below its minimum active member threshold.

If all pool members fail the custom content monitor due to updated content, every member would be marked Offline and the pool would have zero active members, causing it to be marked Offline (red) rather than Available.

When over 25% of pool members fail the custom content monitor because their content no longer matches the expected response, those members are marked Offline - but the remaining members that still pass the monitor satisfy the pool's minimum active member threshold, keeping the pool Available (green).
