-These limits will be raised once we are ready to start charging for this service. If you need higher limits sooner, complete the [Limit Increase Request Form](https://forms.gle/CdueDKvb26mTaepa9). If the limit can be increased, Cloudflare will contact you with next steps.
+The limits for Browser Rendering will continue to be raised over time. In the meantime, Cloudflare will grant [requests for higher limits](https://forms.gle/CdueDKvb26mTaepa9) on a case-by-case basis if a need for a higher limit can be clearly demonstrated.
