Prior Version(s) of Amazon Managed Blockchain Service Level Agreement – Not Currently In Effect
Last Updated: April 17, 2019
This Amazon Managed Blockchain Service Level Agreement (“SLA”) is a policy governing the use of Amazon Managed Blockchain (“Managed Blockchain”) and applies separately to each account using Managed Blockchain. 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 Managed Blockchain available with a Monthly Uptime Percentage for each AWS region, during any monthly billing cycle, of at least 99.9% (the “Service Commitment”). In the event Managed Blockchain 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 Managed Blockchain in the affected AWS region 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 99.99% but equal to or greater than 99.0%
Less than 99.0% but equal to or greater than 95.0%
Less than 95.0%
We will apply any Service Credits only against future Managed Blockchain payments otherwise due from you. At our discretion, we may issue the Service Credits to the credit 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 AWS. Service Credits 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 or non-performance or other failure by us to provide Managed Blockchain 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 will need to 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:
i. the words "SLA Credit Request" in the subject line;
ii. the billing cycle and AWS region(s) with respect to which you are claiming Service Credits, together with the Monthly Uptime Percentage for that AWS region for the billing cycle and the specific dates, times, and Availabilities for each 5-minute interval with less than 100% Availability in that AWS region throughout the billing cycle;
iii. 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.
Managed Blockchain SLA Exclusions
The Service Commitment does not apply to any unavailability, suspension or termination of Managed Blockchain, or any other Managed Blockchain 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 Managed Blockchain; (ii) that result from any voluntary actions or inactions from you or any third party (e.g. errors in chaincode, misconfiguring security groups, VPC configurations, or certificates, etc.); (iii) that result from you not following the best practices described in the Managed Blockchain User Guide on the AWS 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); (v) caused by underlying open source software that lead to repeated software crashes or an inoperable blockchain instance or related service; (vi) related to use of the Managed Blockchain Starter Plan; (vii) related to the use of bc.t3 instance types or other instance classes which have similar CPU and memory resource limitations; or (viii) arising from our suspension or termination of your right to use Managed Blockchain in accordance with the Agreement (collectively, the “Managed Blockchain 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 processed by Managed Blockchain that do not fail with Errors and relate solely to provisioned Managed Blockchain resources. If you did not make any Requests in a given 5-minute interval, that interval is assumed to be 100% available.
- An “Error” is any Request that returns a 500 or 503 error code.
- “Monthly Uptime Percentage” for a given AWS 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 Managed Blockchain SLA Exclusion.
- “Request” is an invocation of a Managed Blockchain API by directly calling the API. This does not include the APIs for supported open source blockchain frameworks.
- A “Service Credit” is a dollar credit, calculated as set forth above, that we may credit back to an eligible account.
