```diff
+ Between 22:32 UTC and 23:11 UTC, a feature disruption impacted Heroku services, which has since been resolved. During the impact window, some Heroku users were unable to create new builds, promote existing releases, or upload slugs manually via the Heroku Platform API. Our investigation identified a recent change as the cause of the issue. To mitigate the impact, we reverted this change to its last known good state.  We will thoroughly investigate the incident, confirming the technical trigger, the underlying cause, and preventive action to avoid a repeat in the future.
