Scheduled
On Monday, October 26, 2020, starting at 14:00 UTC (10:00 EDT), and continuing until 18:00 UTC (4 hours), Heroku will be performing the final brownout of the Cedar-14 build service before the EOL window closure on November 2, 2020.
During the brownout, Cedar-14 apps will continue to run, but customers will not be able to build and deploy new versions of their Cedar-14 apps, emulating the Cedar-14 EOL window closure.
All other non-build functionality such as setting up environment variables, scaling processes, running one-off dynos and managing add-ons will continue to work unaffected. Rollback can be used to address any code regressions during the brownout. More details about what will happen to your applications as part of the Cedar-14 EOL can be found in our FAQ.
We will provide an update when we begin and complete the brownout.
