Amazon WAF Service Level Agreement for Amazon Web Services (Ningxia Region)
Last Updated: June 7, 2021
This Amazon WAF Service Level Agreement for Amazon Web Services China (Ningxia Region) (“SLA”) is a policy governing the use of Amazon WAF 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 Amazon WAF. 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.
We will use commercially reasonable efforts to make Amazon WAF available with a Monthly Uptime Percentage for each Amazon Web Services region, during any monthly billing cycle, of at least 99.95% (the “Service Commitment”). In the event Amazon WAF does not meet the Service 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 WAF 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 are calculated as a percentage of the following charges paid by you for Amazon WAF for the monthly billing cycle in which the Monthly Uptime Percentage for a given Amazon Web Services region fell within the ranges set forth in the table below:
Monthly Uptime Percentage
Service Credit Percentage
Less than 99.95% 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 WAF payments otherwise due from you. At our discretion, we may issue the Service Credits 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. Service Credits 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 WAF is the receipt of Service Credits (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:
- the words “SLA Credit Request” in the subject line;
- the billing cycle and Amazon Web Services regions with respect to which you are claiming Service Credits, together with the Monthly Uptime Percentage for that Amazon Web Services region for the billing cycle and the specific dates, times, and Availabilities for each 5-minute interval with less than 100% Availability in that Amazon Web Services region throughout the billing cycle;
- your Request logs that document the errors for 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 credit request is confirmed by us and is less than the Service Commitment, then we will issue the Service Credits to you within one billing cycle following the month in which the credit request occurred. Your failure to provide the credit request and other information as required above will disqualify you from receiving Service Credits.
Amazon WAF SLA Exclusions
The Service Commitment does not apply to any unavailability, suspension or termination of Amazon WAF, or any other Amazon WAF 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 WAF; (ii) that result from any voluntary actions or inactions from you or any third party; (iii) that result from your failing to follow the best practices described in the Amazon WAF User Guide on the Amazon Web Services China Site; (iv) that result from your equipment, software or other technology and/or third party equipment, software or other technology (other than third party equipment within our direct control); or (v) arising from our suspension or termination of your right to use Amazon WAF in accordance with the Agreement (collectively, the “Amazon WAF 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.
- “Availability” is calculated for each 5-minute interval as the percentage of Requests inspected by Amazon WAF that do not fail with Errors and relate solely to Amazon WAF Requests that are associated with underlying Host Services. If your respective Host Services did not make any Requests for inspection by Amazon WAF in a given 5-minute interval, that interval is assumed to be 100% available.
- An “Error” is any Request that Amazon WAF failed to inspect, reported by underlying Host Services in their respective access logs.
- “Host Services” are Amazon CloudFront, Amazon Application Load Balancer, and Amazon API Gateway.
- “Monthly Uptime Percentage” for a given Amazon Web Services region is calculated as the average of the Availability for all 5-minute intervals in a monthly billing cycle. Monthly Uptime Percentage measurements exclude downtime resulting directly or indirectly from any Amazon WAF SLA Exclusions.
- “Request” means an inbound HTTP request.
- A “Service Credit” is a Renminbi credit, calculated as set forth above, that we may credit back to an eligible account.
