Autoscaling now more responsive to traffic lulls

Change effective on 08 February 2017

We’ve optimized the Autoscaling algorithm to scale down more rapidly when traffic dips. If there is no request throughput for at least 3 minutes, dynos will be scaled down at 1 minute intervals until traffic resumes. More information on Autoscaling is available in Dev Center.

Heroku Update
Starting November 28th, 2022, free Heroku Dynos, free Heroku Postgres, and free Heroku Data for Redis® will no longer be available. If you have apps using any of these resources, you must upgrade to paid plans by this date to ensure your apps continue to run and to retain your data.

Eligible students can apply for platform credits through our new Heroku for GitHub Students program.
