Api.materialsproject.org blocks some IP ranges of AWS?

mp-api fails by 403 error on some instances in AWS ap-northeast-1 region and us-west-2 region, but it works in us-east-1. I guess Cloudflare might blocks them as suspicious access.
Can anyone check if Cloudflare works as expected?
Thank you.

Hi @ksauzz,

yes, we recently blocked AWS and GCP networks since the majority of requests we got from cloud environments were inefficient and mostly unnecessary duplicate downloads. We recommend that users download the data they need from MP once, save it to disk, and then run their applications based a downloaded version of the data. If there’s a legitimate use case that you’d like us to support, please reach out to us with a description via email.

Thank you for the quick response. I understood your concerns. We will reach out to your team to explain our use case later via the email.
