Hi! I’m a product manager here at CircleCI. I wanted to provide a small FYI for transparency’s sake, no action required. CircleCI is commencing the roll-out out of a new implementation of how the Docker Layer Caching (DLC) feature works “under the hood”. Users should see minimal impact.
If you see any anomalies with how your jobs that enable DLC are executing, please file a support ticket immediately and do not hesitate to comment on this thread below.
The new implementation I mentioned above was not rolled out in early July.
The rollout is commencing now. Based on internal testing, the majority of jobs should see no negative impact. If you are having issues with DLC, please comment on this thread and open a support ticket via https://support.circleci.com/hc/en-us
