# Alertmanager Cluster Failed To Send Alerts
## Meaning
All instances failed to send notification to a critical integration.
## Impact
You will not receive notification when an alert is raised.
## Diagnosis
No alerts are received at the integration level from the cluster.
## Mitigation
Depending on the integration, correct the integration with the faulty instance (network, authorization token, firewall...)
