We implemented an incremental region-based update to the rules. However, after receiving reports of false positives, we rolled back the changes on the morning of 1/27 EST. Currently, we are working on fine-tuning and adjusting the rules, and we will share an update before deploying them again. In the meantime, we kindly request you to share the false positive data, as it will be helpful for further investigation and refinement. We apologize for the disruption caused to the service.

    hi SivaG​ ,

     

    Thanks for the update. We would like to know when these rules will get updated. If not for a notification, we would like a link to the changelog so that we can determine why this is happening. Can you provide a link for the change log/version update of these rules?

    I will not be able to share any data, but these are the rules that were blocking the requests.
