This issue is now resolved.

Our demo (https://demo.poool.fr), our website (https://poool.fr) and our auth platform (https://id.poool.fr) are also impacted by this issue. Heroku is still investigating.

Our front cloud provider (Heroku) is having routing issues since 11 AM (GMT), so you will be randomly routed to non existing application container, e.g not running our Dashboard. Heroku is dealing with the issue right now, and everything might work as expected in a few minutes. (https://status.heroku.com/incidents/1533)
