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 requirements:

  • 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.

  • 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 GET /api/v2/clients)

  • 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

Email considerations

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

Test requirements

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.
