# Alerts

An alert opens when the hub reports something that breaks a policy, or goes quiet for ten minutes. Alerts stay open until the condition clears, and critical ones are emailed.

## Working with alerts

Views: **All alerts**, **New**, **Critical** and **Resolved**. Open an alert to see what it is about, its severity, what happened (became critical, acknowledged, resolved), and what the hub reported. Select **Acknowledge** to show your team you are on it; the alert stays open until its condition clears.

Critical alerts are emailed to everyone with Manage liquidity, and operation alerts also to everyone with Approve signing.
