  * The ETL process runs at 7am (UK time) in production.

  * The ETL process runs at 1pm (UK time) in integration.
  * **All dates for the rake tasks below are inclusive.** In other words, if you

  * The rake task should be run on the `content-data-api` TARGET_APPLICATION and the `backend` MACHINE_CLASS.
