There will be five stages.

As of today (Mar 13th, 2024) we will stop granting new API access keys. All pending applications will be rejected. 
On March 27th, 2024 we will stop accepting POST data submissions to the API. All submissions will receive a 403 response and the submitted data will be discarded. Additionally, we will stop publishing new exports of cell data for download. 
On April 10th, 2024 the cell data downloads will be deleted and will no longer be available. 
On June 12th, 2024 third party API keys will be removed and the service will only be available for Mozilla’s use cases. 
On July 31st, 2024 this source repo (https://github.com/mozilla/ichnaea) will be archived.
