SERVICE LEVEL AGREEMENT (SLA)
Last Updated: May 2026
Introduction
This Service Level Agreement ("SLA") delineates the service levels for Weaviate's vector database services. The infrastructure of the services is designed for Normal Use, and the Availability is applicable solely for Normal Use of the services. Any usage beyond Normal Use may lead to a degradation of service quality and availability. Issues accessing the service due to application errors (like misuse, misconfiguration, etc.) are excluded from Availability calculations and are not considered downtime as these are the responsibility of the Customer.
Normal Use
Normal Use refers to the utilization of the service within the parameters outlined in our official documentation. The specifics of these parameters, including any limitations or restrictions, are detailed in the documentation available to all customers. In instances where a customer wishes to operate outside of these parameters, arrangements can be discussed and agreed upon in writing between the parties. For further details, please refer to our documentation.
Definitions and Calculations

| Parameter | Flex | Plus | Premium (Shared Deployment) | Premium (Dedicated Deployment) |
|---|---|---|---|---|
| Availability per Quarter | 99.5% | 99.9% | 99.9% | 99.95% |

| Availability per Quarter | 99.5% | 99.5% | 99.5% |
Non-Availability
Non-Availability refers to periods where the service level indicators are not consistently achieved as defined below. The formal commencement of non-availability begins from the time the monitoring systems indicate such status or when the Customer notifies Weaviate at support@weaviate.io. This period concludes when Weaviate confirms the restoration of availability either through an email to the customer or an update on the relevant status page.
Service Level Indicators (SLIs)
The performance of the services is measured in regular intervals with the service receiving a status of Non-Availability if the SLI tests fail to achieve the expected result in three consecutive tests.
SLI Tests
| Test # | SLI Test | How to test | Expected Result | Test interval |
|---|---|---|---|---|
| 1 | Data Ingest | A new object is added via API to a Weaviate schema | A response of less than 1000 ms with a HTTP status code of 200 | Every (3) minutes |
| 2 | Data Query | The Weaviate API is queried for an existing object | A response of less than 1000 ms with a HTTP status code of 200 | Every (3) minutes |
Reaction Time
Upon becoming aware of a Non-Availability status, Weaviate will immediately address the issue and strive to initiate remediation efforts.
Planned Maintenance Windows
Planned maintenance windows are periods during which the availability of the services may be impacted due to scheduled maintenance activities. These windows are notified at least one week in advance to the Customer via email. Maintenance necessary to maintain operational safety due to unpredictable external circumstances may be carried out outside of these windows with immediate notification to the Customer.
