Incident Review: Intermittent Disruption and Degradation of Heroku Services on October 20, 2025

Beginning on October 20th, 2025 07:06 UTC, multiple Heroku services were initially impacted by a database service disruption with our cloud infrastructure provider in the Virginia region. This affected the monitoring, provisioning, networking and availability of cloud infrastructure services that power the Heroku platform. This outage was a complex, multi-phased event primarily triggered by multiple upstream outages within the cloud infrastructure provider Virginia region, and compounded by Heroku’s single-region control plane architecture and automation failures.
