Are dependencies caches always stored into AWS S3 Infrastructure (us-west-1 region)?

[remmerci1]

Hi,

I found an answer from 2022 and I would like to know if this is always true: https://community.atlassian.com/forums/Bitbucket-questions/Re-Where-is-Dependency-caches-stored/qaq-p/2057210/comment-id/82955#M82955

I run builds on self-hosted runners (AWS ca-central-1) and I would like to optimize transfert costs. Caches downloads before each step and each build result in a certain cost. If I create a VPC Endpoint Service between my VPC and s3.us-west-1.amazon.com, caches downloads should be done by using internal AWS network without transit by NAT Gateway (less expensive).

Thanks,

Remi
