Escalation and silence policies centrally manage how alerts are handled during version and feature upgrades, canary releases, and maintenance windows, preventing unnecessary alerts and alert storms. Escalation policies are often paired with silence policies: to suppress notifications for alerts during an upgrade, use a silence policy.
Key rule: Silence policies are evaluated before notification policies. An alert event is first matched against silence policies. If a match is found, the event is silenced and skips all subsequent notification processing.

Configuration examples
Example 1: Silence for a one-time upgrade window
Use case: Silence alerts related to the order-service during an upgrade from 01:00 to 03:00 on February 10, 2026.
-
Effective Scope: Service Name = order-service (You can add other conditions, such as Environment = Production or Region = China (Hangzhou)).
-
Effective Method: One-time (01:00–03:00).
Example 2: Canary release with a compound condition
Use case: Manage alerts during a simultaneous upgrade of Service A in China (Hangzhou) and Service B in China (Beijing).
Compound Expression: (1 AND 2) OR (3 AND 4), which pairs a region with a service name.
Usage notes
-
To suppress notifications during an upgrade, use a silence policy. Ensure the silence window covers the entire upgrade duration, preferably with a buffer before and after.
-
An event may match multiple policies. If it matches any silence policy, the event is silenced.
