## AI overview

Heroku reviews a complex, multi-phase service disruption beginning on October 20, 2025. The incident was triggered by database and networking outages at its cloud infrastructure provider in Virginia and compounded by Heroku's single-region control plane architecture and automation failures, affecting provisioning, monitoring, networking, availability, API operations, dynos, builds, and deployments.

## Source excerpt

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. The service disruptions can be divided into two distinct phases based on root causes, timeline, and impacts.
