Service Level Agreement for AWS Key Management Service
Last Updated: March 6, 2019
This Service Level Agreement (“SLA”) for AWS Key Management Service is a policy governing the use of AWS Key Management Service (“AWS KMS”) and applies separately to each account using AWS KMS. In the event of a conflict between the terms of this SLA and the terms of the AWS Customer Agreement or other agreement with us governing your use of our Services (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.
AWS will use commercially reasonable efforts to make AWS KMS available with the applicable Monthly Uptime Percentage during any monthly billing cycle (the “Service Commitment”). In the event AWS KMS does not meet the Service Commitment, you will be eligible to receive a Service Credit as described below.
Service Credits are calculated as a percentage of the total charges paid by you for AWS KMS for the billing cycle in which the error occurred 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%||100%|
We will apply any Service Credits only against future AWS KMS payments otherwise due from you. At our discretion, we may issue the Service Credit to the credit card you used to pay for the billing cycle in which the error occurred. Service Credits will not entitle you to any refund or other payment from AWS. A Service Credit will be applicable and issued only if the credit amount for the applicable monthly billing cycle is greater than one dollar ($1 USD). 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, non-performance, or other failure by us to provide AWS KMS 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 AWS 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 incident of non-zero Error Rates that you are claiming; and
3. 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 applicable to the month of such request is confirmed by us and is less than the applicable Service Commitment, then we will issue the Service Credit to you within one billing cycle following the month in which your request is confirmed by us. Your failure to provide the request and other information as required above will disqualify you from receiving a Service Credit.
AWS KMS SLA Exclusions
The Service Commitment does not apply to any unavailability, suspension or termination of AWS KMS, or any other AWS KMS 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 AWS KMS; (ii) that result from any actions or inactions of you or any third party; (iii) 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 (iv) arising from our suspension and termination of your right to use AWS KMS in accordance with the Agreement (collectively, the “AWS KMS SLA Exclusions”). If availability is impacted by factors other than those used in our calculation of the Error Rate, then we may issue a Service Credit considering such factors at our discretion.
- “Error Rate” means: (i) the total number of internal server errors returned by AWS KMS as error status “InternalError” or “ServiceUnavailable” divided by (ii) the total number of requests for the applicable request type during that five minute interval. We will calculate the Error Rate for each AWS KMS account as a percentage for each five minute interval in the monthly billing cycle. The calculation of the number of internal server errors will not include errors that arise directly or indirectly as a result of any of the AWS KMS SLA Exclusions.
- “Monthly Uptime Percentage” is calculated by subtracting from 100% the average of the Error Rates from each five minute interval in the monthly billing cycle.
- “Service Credit” means a dollar credit, calculated as set forth above, that we may credit back to an eligible AWS KMS account.
