Documentation quickstart backend rails example missing

https://auth0.com/docs/quickstart/backend/rails I get a 404 when I look for the backend rails example. Was it taken down?

Hi Patric, we are updating our quick start applications. We apologize for the inconvenience this has caused. There is now a notice for this update instead of a 404 error.

Do you have any idea of when this will be updated ( 1 day, 1 week, 1 month ) ?
