What AWS service provides a 100% availability SLA?

This Amazon Compute Service Level Agreement for Amazon Web Services (Ningxia Region) (this “SLA”) is a policy governing the use of the Included Services (listed below) under the terms of the Western Cloud Data Customer Agreement for Amazon Web Services (Ningxia Region) (available at https://www.amazonaws.cn/agreement/ningxia and as updated from time to time, collectively with other agreements with us governing your use of our Services, the “Agreement”) between Ningxia Western Cloud Data Technology Co., Ltd. (“Western Cloud Data”, “us” or “we”) and you. This SLA applies separately to each account using the Included Services. In the event of a conflict between the terms of this SLA and the Agreement, the terms and conditions of this SLA apply, but only to the extent of such conflict. Capitalized terms used herein but not defined herein shall have the meanings set forth in the Agreement.

Included Services

• Amazon Elastic Compute Cloud (Amazon EC2)*
• Amazon Elastic Block Store (Amazon EBS)
• Amazon Elastic Container Service (Amazon ECS)
• Amazon Fargate for Amazon ECS and Amazon EKS

*For purposes of this SLA, Amazon EC2 includes any Amazon Elastic Graphics, Amazon Elastic Inference, and Elastic IP Address resources purchased with the relevant Amazon EC2 instance(s).

SLAs

We makes two SLA commitments for the Included Services: (1) a Region-Level SLA that governs Included Services deployed across multiple AZs, and (2) an Instance-Level SLA that governs Amazon EC2 instances individually. Service Credits provided to you under this SLA will be provided to you only in connection with your use of Included Services from Amazon Web Services China (Ningxia) region. This SLA does not authorize you to receive any Service Credits from any other Amazon Web Services regions.

Region-Level SLA

For Included Services with all running instances or tasks deployed concurrently across two or more AZs, we will use commercially reasonable efforts to make each Included Service available with a Monthly Uptime Percentage of at least 99.99%, in each case during any monthly billing cycle (the “Region-Level SLA”). In the event any of the Included Services do not meet the Region-Level SLA, you will be eligible to receive a Service Credit as described below.

Instance-Level SLA

For each individual Amazon EC2 instance (“Single EC2 Instance”), we will use commercially reasonable efforts to make the Single EC2 Instance available with an Instance-Level Uptime Percentage of at least 99.5%, in each case during any monthly billing cycle (the “Instance-Level SLA”). In the event any Single EC2 Instance does not meet the Instance-Level SLA, you will be eligible to receive a Service Credit as described below.

Note: In addition to the Instance-Level SLA, we will not charge you for any Single EC2 Instance that is Unavailable for more than six minutes of a clockhour. This applies automatically and you do not need to request credit for any such hour with more than six minutes of Unavailability.

SLA Credits

Service Credits are calculated as a percentage of the monthly bill (excluding one-time payments such as upfront payments made for Reserved Instances) for the individual Included Service that did not meet the Region-Level SLA, or for the Single EC2 Instance that did not meet the Instance-Level SLA, respectively.

We will apply any Service Credits only against future payments for the applicable Included Service otherwise due from you. At our discretion, we may issue the Service Credit to the bank card you used to pay for the billing cycle in which the Unavailability occurred. Service Credits will not entitle you to any refund or other payment from us. A Service Credit will be applicable and issued only if the credit amount for the applicable monthly billing cycle is greater than one Renminbi (¥1 Renminbi). Service Credits may not be transferred or applied to any other account.

Credit Request and Payment Procedures

To receive a Service Credit, you must submit a claim by opening a case in the Amazon Web Services Support Center. You may only submit a claim under either the Region-Level SLA or the Instance-Level SLA, as these claims cannot be combined or stacked for a particular Single EC2 Instance. Your credit request must be received by us by the end of the second billing cycle after which the incident occurred and must include the information specified below for the Region-Level SLA and Instance-Level SLA, respectively. 

Region-Level SLA requests must include:

1. the words “SLA Credit Request – Region-Level Claim” in the subject line;
2. the dates and times of each Unavailability incident that you are claiming;
3. the resource IDs for the affected Included Service; and
4. your request logs that document the errors and corroborate your claimed outage**.

Instance-Level SLA requests must include: 

1. the words “SLA Credit Request – Instance-Level Claim” in the subject line;
2. the dates, times, and the affected AZ of each Unavailability incident that you are claiming;
3. the resource IDs for the affected Single EC2 Instances; and
4. your request logs and other data necessary for us to validate your claimed outage**.

** Please replace any confidential or sensitive information with asterisks.

If a claim under the Region-Level or Instance-Level SLA is confirmed by us as valid, we will issue you a Service Credit within one billing cycle following the month in which your request is confirmed by us.

Your failure to provide the requested and other information as required above will disqualify you from receiving a Service Credit. Unless otherwise provided in the Agreement, this SLA sets forth your sole and exclusive remedies, and our sole and exclusive obligations, for any unavailability, non-performance, or other failure by us to provide the Included Services.
