Service Level for Yandex Managed Service for Apache Airflow™

This document defines Service Level of Yandex Managed Service for Apache Airflow™ (“Service”) and is an integral part of Yandex.Cloud Customer Agreement (“Agreement”) and SLA available at: https://yandex.com/legal/cloud_sla. Capitalized terms used herein but not defined herein shall have the meanings set forth in Agreement and Linked Documents.

Compensation Amount:

Definition of Service Unavailability:

“Unavailability of the Service” is fixed when the Error Rate exceeds 5% on the Platform side;

The “error rate" is measured using the following formula: the number of requests that returned error code 500, 503 or the message "Internal Server Error" or gRPC Status 13 with error code "INTERNAL", divided by the total number of Correct requests for the same time period. Requests that violate the requirements of a Deferred request are not taken into account in the formula;

“Service Unavailability Period” means 10 consecutive minutes during which the Unavailability of the Service was recorded;

“Correct request” is a request that corresponds to the documentation of the Service, which, if the Service is working, returns a response that does not contain an error;

"Deferred request" means the Customer's need to maintain a time interval between requests to the server, if an error occurs. The waiting periods according to the rules of the Deferred request must be at least 1 second for the first recurring request and for each subsequent request, the time interval increases exponentially up to 32 seconds before each subsequent request.

The Service Level Agreement does not apply to cases of Unavailability of the Service that occurred due to circumstances beyond Yandex's control, including in connection with failures of external networks or non-compliance with Instructions by the Customer.
