Amazon WorkSpaces Service Level Agreement for Amazon Web Services (Ningxia Region)

Last Updated: November 3, 2021

This Amazon WorkSpaces Service Level Agreement for Amazon Web Services (Ningxia Region) (“SLA”) is a policy governing the use of Amazon WorkSpaces under the terms of the Western Cloud Data Customer Agreement for Amazon Web Services (Ningxia Region) (available at 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 Amazon WorkSpaces. In the event of a conflict between the terms of this SLA and the terms of 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.

Service Commitment

We will use commercially reasonable efforts to make Amazon WorkSpaces available with a Monthly Uptime Percentage of at least 99.9% for each Account in an Amazon Web Services region during any monthly billing cycle (the "Service Commitment"). In the event Amazon WorkSpaces does not meet the Monthly Uptime Percentage commitment, you will be eligible to receive a Service Credit as described below. The Service Commitment and Service Credits provided to you under this SLA will be provided to you only in connection with your use of Amazon WorkSpaces from Amazon Web Services China (Ningxia) region. This SLA does not authorize you to receive any Service Commitment or Service Credits from any other Amazon Web Services regions.

Service Credits

Service Credits are calculated as a percentage of the charges paid by you for all Amazon WorkSpaces that did not meet the Monthly Uptime Percentage commitment in a billing cycle in accordance with the schedule below.

Monthly Uptime Percentage

Service Credit Percentage

Less than 99.9% but greater than or equal to 99.0%


Less than 99.0% but greater than or equal to 95.0%


Less than 95.0%


We will apply any Service Credits only against future Amazon WorkSpaces payments 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. Unless otherwise provided in the Agreement, your sole and exclusive remedy for any unavailability or non-performance or other failure by us to provide Amazon WorkSpaces is the receipt of a Service Credit (if eligible) in accordance with the terms of this SLA.

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. To be eligible, the credit request must be received by us by the end of the second billing cycle after which the incident occurred and must include:

  1. the words "SLA Credit Request" in the subject line;
  2. the dates and times of each Unavailability incident you are claiming;
  3. the Amazon WorkSpaces IDs falling below the Amazon WorkSpaces SLA; and
  4. your request logs that document the errors and corroborate your claimed outage (any confidential or sensitive information in these logs should be removed or replaced with asterisks).

If the Monthly Uptime Percentage of such request is confirmed by us and is less than the Service Commitment, then we will issue the Service Credit to you within one billing cycle following the month in which the request occurred. Your failure to provide the request and other information as required above will disqualify you from receiving a Service Credit.

Amazon WorkSpaces SLA Exclusions

The Service Commitment does not apply to any unavailability, suspension or termination of Amazon WorkSpaces, or any other Amazon WorkSpaces performance issues: (i) caused by factors outside of our reasonable control, including any force majeure event or Internet access or related problems beyond the demarcation point of Amazon WorkSpaces; (ii) that result from any actions or inactions from you or any third party; (iii) that result from failure to follow the guidelines or exceeding the limitations described in the Amazon WorkSpaces Documentation on the Amazon Web Services China Site; (iv) that result from WorkSpaces in an Inoperable state; (v) that result from failures prior to or during authentication to the Amazon WorkSpaces service; (vi) that result from client application (non-server) failures; (vii) that result from your equipment, software or other technology and/or third party equipment, software or other technology (other than third party equipment beyond our direct control); (viii) that result from any maintenance as provided for pursuant to the Agreement; and (ix) arising from our suspension or termination of your right to use Amazon WorkSpaces in accordance with the Agreement (collectively, the "Amazon WorkSpaces SLA Exclusions"). If availability is impacted by factors other than those explicitly used in our Monthly Uptime Percentage calculation, then we may issue a Service Credit considering such factors at our discretion.


• “Available” means that a WorkSpace was not “Unavailable” during a 1 minute interval.
• "Monthly Uptime Percentage” for a given Account in an Amazon Web Services region is calculated by the average percentage of all Available WorkSpaces for the Account in the Amazon Web Services region (availability measured in 1 minute intervals) during the monthly billing cycle. Each Amazon WorkSpace is assumed to be 100% Available if there were no connection attempts during a 1 minute interval. Monthly Uptime Percentage measurements exclude unavailability resulting directly or indirectly from any Amazon WorkSpaces SLA Exclusion.
• A "Service Credit" is a Renminbi credit, calculated as set forth above, that we may credit back to an eligible account for WorkSpaces in the Amazon Web Services region which falls below the Monthly Uptime Percentage.
• “Unavailable” means that all connection events for a WorkSpace were unsuccessful during a 1 minute interval.
