Scheduled

We will be performing an emergency maintenance in order to update the Docker Infrastructure that supports our `working_directory: /mnt/ramdisk` feature. This is a necessary step in order for critical work in the near term.

This will be a breaking change for any Docker jobs utilizing `working_directory: /mnt/ramdisk`. Jobs will fail on checkout and workspace attachments.

The immediate workaround will be to remove any usage of `working_directory: /mnt/ramdisk` from your job which will require an update of `.circleci/config.yml`

Once this maintenance is complete, customers will be unable to utilize `working_directory: /mnt/ramdisk`until further notice.
