1.Definition

Service Cycle: One Service Cycle equals to one calendar month. If the service is used for less than one calendar month, the Service Cycle will be calculated as one calendar month.
Service Cycle in Minutes: Calculated on the basis of the total number of days in a Service Cycle × 24 (hours) × 60 (minutes).
Service Unavailability: The service is deemed unavailable if the condition below is met and the situation lasts for 5 minutes or longer. A time duration less than 5 minutes is not counted as Service Unavailability.
Kubernetes API Service Unavailability: The Kubernetes API service cannot be connected or does not respond to your requests, excluding the following circumstances:
(1)Service upgrades, modification, and maintenance made by Kingsoft Cloud with a prior notification to you;
(2)Service unavailability due to your own operation, e.g. restarting the core components of a Kubernetes cluster, etc.;
(3)Service unavailability caused by the failure of a product that KCE relies on, e.g. Kingsoft Cloud Elastic Compute (“KEC”), Elastic Physical Compute (“EPC”), Server Load Balancing (“SLB”), etc.
Service Downtime: The total time of Service Unavailability within a Service Cycle, calculated by minutes.
Calculation of Service Availability: Service Availability = (Service Cycle in Minutes - Service Downtime) / Service Cycle in Minutes × 100%
