AWS Hybrid Storage and Data Transfer Service Level Agreement
Last Updated: April 5, 2023
This AWS Hybrid Storage and Data Transfer Service Level Agreement (“SLA”) is a policy governing the use of the Included Services (listed below) and applies separately to each account using the Included Services. 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 Storage Gateway
- AWS DataSync
- AWS Transfer Family
AWS will use commercially reasonable efforts to make the Included Services each available with a Monthly Uptime Percentage, as described below, during any monthly billing cycle (the “Service Commitment”). In the event an Included Service 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 the applicable Included Service in the AWS region affected for the monthly billing cycle in which the Monthly Uptime Percentage fell within the ranges set forth in the table below.
|Monthly Uptime Percentage||Service Credit Percentage|
|Less than 99.9% but equal to or greater than 99.0%||10%|
|Less than 99.0% but greater than or equal to 95.0%||25%|
|Less than 95.0%||100%|
We will apply any Service Credits only against future payments otherwise due from you for the Included Service. At our discretion, we may issue the Service Credit to the credit card you used to pay for the billing cycle in which the Included Service did not meet the Service Commitment. 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 the Included Services 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:
- the words “SLA Credit Request” in the subject line;
- the billing cycle and AWS region with respect to which you are claiming Service Credits together with the dates and times of each incident of non-zero Error Rates that you are claiming; and
- your request logs that document the claimed incident(s) when the Included Service did not meet the Service Commitment (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 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 Hybrid Storage and Data Transfer SLA Exclusions
The Service Commitment does not apply to any unavailability, suspension or termination of an Included Service, or any other Included Service 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 the Included Service; (ii) that result from any actions or inactions of you; (iii) that result from your equipment, software or other technology; (iv) that result from you not following the current technical documentation applicable to the Included Services (including the applicable developer guides) as posted by us and updated by us from time to time on the AWS Site; or (v) arising from our suspension or termination of your right to use the Included Service in accordance with the Agreement (collectively, the “AWS Hybrid Storage and Data Transfer SLA Exclusions”). If availability is impacted by factors other than those used in our calculation of Monthly Uptime Percentage, then we may issue a Service Credit considering such factors at our discretion.
- “Error Rate” means: (i) the total number of internal server errors related to read/write operations returned by the Included Service as error status HTTP 500 or 503 (Server Error code) divided by (ii) the total number of requests for the applicable request type during that 5-minute interval. We will calculate the Error Rate for each Included Service account as a percentage for each 5-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 Hybrid Storage and Data Transfer SLA Exclusions.
- “Monthly Uptime Percentage” is calculated by subtracting from 100% the average of the Error Rates from each 5-minute interval in the monthly billing cycle. If you have been running an Included Service for only part of a month the Error Rate is assumed to be 0% during the portion of the month that the Included Service was not running.
- A “Service Credit” is a dollar credit, calculated as set forth above, that we may credit back to an eligible Included Service account.
