Fair usage limits

Read about our fair usage limits to keep service quality predictable for everyone.

Fair usage limits are designed to allow for normal "unlimited" use of the service while preventing abuse and ensuring a good experience for all users. These limits are enforced to maintain service quality and reliability for everyone, and may change at any time.

If you plan to use the service in a way that may approach or exceed these limits, please contact us to increase them or discuss a custom plan. We are happy to work with you to find a solution that fits your needs, whether it's a temporary increase, a custom plan, or other accommodations. Please reach out to us if you have any questions or concerns about fair usage limits or if you need assistance with your specific use case.

These limits might be raised in the future as we continue to optimise our infrastructure and expand our capacity, but they are in place to ensure a consistent and reliable experience for all users. We appreciate your understanding and cooperation in adhering to these limits.
