We currently have an escalation policy that alerts on 6 layers, each escalation with a timeout period of 15 minutes. Question is based on an example below. As we move through the layers, when layer 3 gets an alert, does everyone above (layer1&2) get alerted? If not, is there a possibility to set this up?
Layer 1 alert > does not respond > 15 minutes > escalate
Layer 2 alert > does not respond > 15 minutes > escalate
Layer 3 alert > does respond
