Load Testing Policy
Effective Date: 4 February 2019
Auth0 recognizes that customers may occasionally need to perform load tests against its production cloud service. In order to ensure a successful test and maintain a high quality of service for all customers, Auth0 has established the following guidelines. Any load testing in Auth0 must be conducted in accordance with this Policy.
Only customers who have purchased an Enterprise subscription may conduct load testing. Customers with an Enterprise subscription may request one load test (with up to 2 repeats) per year against an Auth0 production tenant. Performance and load testing are only allowed with Auth0's prior written approval. Once approved, testing can only target tenants that we have approved.
Holiday load testing policy
Updated: November 1, 2022
During the holiday season, load testing requests must meet the following:
Be filed at least 2 weeks prior to the desired test date. 1 month or more of advance notice is preferred to ensure time for a thorough review and any required modifications.
Approved load tests are permitted only on Tuesdays, Wednesdays and Thursdays during off peak hours for the targeted environment.
Load tests will not be allowed during Red Change Freeze periods.
Red Code Freeze Dates for Q4 2023 are 2023-11-23 to 2023-11-27 and 2023-12-22 to 2023-01-02 (inclusive).
Any requested exceptions require approval of the Senior Vice President of Engineering and the Senior Vice President of Customer Success.
Previously approved load tests that fall within a Red Change Freeze have been rescheduled.
If all RPS requests are determined to be safely within the RPS limits, the load test will be allowed, as long as it has been reviewed and approved by all product/platform teams owning the endpoints being tested.
Tests that fall outside the safe RPS will be rejected.
Only one load test per customer, per environment will be scheduled in a single day.
If there’s a need to run more than one test at a time, the request must be escalated and approved by a Platform Director or Vice President.
Submit load testing request
You must file a load testing request via the Support Center. Under the Issue type field, select I have a question regarding my Auth0 account then select I would like to file a Load Testing Request.
To be considered for approval, the request must:
Be filed at least 2 weeks prior to the desired test date; in many cases, Auth0 encourages one 1 month of advance notice to ensure time for a thorough review and any required modifications.
Be approved in writing before any testing is conducted.
Stay within our published production rate limits.
Include all information described below.
Information to include in requests
The load testing request must include the following:
A description of the test to be done
The name and region of the Auth0 tenant to be used during the test
The requested date and time of the test, including time zone
The requested duration of the test (2 hours maximum)
The platforms to be used for the test (desktop/laptop, iOS, Android, other)
The Auth0 features (such as rules or email) used during the test
The Auth0 API methods and endpoints to be used (for example
The maximum requests per second for each type of request or endpoint
The types of Auth0 connections involved in the test
Whether you are using a custom domain
Which Auth0 Rules, if any, will execute during the test
Which Custom DB, if any, will be used
Which Auth0 Webtasks, if any, will be used
Whether verification, welcome or other emails will be sent
The peak load, specified in requests-per-second, expected for each API endpoint or Auth0 feature involved in the test
An explanation/justification for the peak load numbers, including the size of the target user population and realistic estimates of logins per hour
The ramp-up rate for the test
Contacts who will be available during the test and how to reach them
Number of unique users participating in the load test
Before any testing, customers must:
Configure their own email provider in Auth0
Receive approval from their email provider to send the expected volume of email
Make arrangements for bounced emails
Establish a mechanism for testing that emails arrived
Load testing windows are subject to availability so advance notice is highly recommended. Once approved, load testing windows will have a scheduled start and end time not to exceed two (2) hours in duration. All testing must begin and end during this window.
Auth0 strongly recommends including a brief "ramp-up" period to the desired load test target numbers. For example, a load test request of 100 RPS might be preceded by three five-minute periods: 5 minutes at 25 RPS, 5 minutes at 50 RPS, and 5 minutes at 75 RPS. This ramp-up period allows Auth0 and the customer to observe and compare effects at increasing RPS levels prior to peak RPS. If a ramp-up period is not possible, please indicate why.
Acceptable testing windows
Public cloud customers must arrange to conduct their load tests during the following off-peak test windows:
prod-au: 9:00 - 17:00 UTC
prod-eu: 21:00 - 5:00 UTC
prod-us: 2:00 - 10:00 UTC
prod-jp: 14:00 - 22:00 UTC
In very exceptional circumstances, Auth0 may grant exceptions to this rule.
