This SLA only applies to your purchase and use of the Services for a fee, and shall not apply to any free Services or trial Services provided by us.

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%

2.Service Availability Guarantee

Kubernetes API service availability will be no less than 99.9%.

Other paid cloud products you use together with KCE will subject to their relevant service level agreements. For example, the following circumstances that are caused by failures of other cloud products are excluded from calculation of Kubernetes API service availability:

(1)Your service is affected because the KEC product you purchased is unavailable;

(2)Your service is affected because the EPC product you purchased is unavailable;

(3)Your service is inaccessible because the SLB product you purchased is unavailable;

(4)Your service data is inaccessible because the Elastic Block Storage (“EBS”) product you purchased is unavailable;

(5)Your service is inaccessible because the Elastic IP (“EIP”) product you purchased is unavailable.
