Scheduled
On Tuesday, October 26, starting at 16:00 UTC (noon EDT), and continuing until 23:59 UTC (19:59 EDT, 8 hours), Heroku will be denying traffic from all SSL Endpoints.
During this time, apps with SSL Endpoints that have custom domains pointing to SSL Endpoint DNS targets will experience outages for the duration of this incident.
For information on migrating off an SSL Endpoint still in use, please see https://help.heroku.com/W63FUHE5/how-do-i-manually-migrate-off-my-ssl-endpoint-add-on
We will provide an update when we begin and complete the service degradation.
