# Incident Report: Database Outage (Log Collector Misconfiguration) ## What Happened Vapi experienced a large service outage causing voice calls to fail and the dashboard to become unavailable. This was caused by a failure in an audit log collector in the Vapi production database. The triggering event was an `apply_config` that our database provider executed at 6:44 AM PST. A misconfiguration in the project-wide telemetry settings caused Postgres processes to become stuck writing to syslog when accepting new connections, exhausting the connection pool and rendering the database unable to accept traffic, including from within the pod itself. We notified our provider's support line at 8:10 AM PST. The root cause was identified at 10:03 AM PST by our database provider. Mitigation was applied by disabling the OTEL connection and restarting the endpoint, after which the system returned to a normal state. A fix to the audit collectors was subsequently published and confirmed stable. ## Customer Impact - **Service availability:** Large outage. Vapi's voice services were unavailable during the incident window, affecting 100% of customers from 7:12 AM PT until 11:49 AM PT when the incident was marked as resolved. - The Vapi dashboard was also unavailable during that time. ## Timeline (PST) | Time | Event | |------|-------| | 6:44 AM | Our database provider executes an `apply_config` change, triggering the incident. | | 7:12 AM | Vapi begins to observe call degradation. | | 7:22 AM | The team begins its investigation. | | 7:43 AM | Vapi updates the status page to notify customers of observed degradation. | | 7:53 AM | Vapi updates the status page to confirm a full outage of both voice calls and the dashboard. | | 8:10 AM | Vapi suspects production database behavior as the source of the problem and notifies the database provider's support team. Initial investigation begins; a large spike in waiting-status connections is observed. | | 8:16 AM | Internal escalation with the database provider for increased urgency. | | 8:29 AM | Vapi confirms production database behavior as the source of the problem on the status page and continues to collaborate with the database provider on mitigation. | | 9:35–10:00 AM | A brief recovery is observed after restarting the database, but degradation reappears after services are scaled back up. | | 10:03 AM | Database provider identifies the root cause: Postgres processes stuck on syslog writes during connection acceptance, caused by a misconfigured project-wide `telemetry_setting` for log collectors. | | 10:03 AM+ | OTEL connection disabled; endpoint restarted; system returns to normal state. | | 10:38 AM | Vapi increases traffic back on the weekly environment and confirms that service is restored. | | 11:09 AM | Vapi increases traffic back on the daily environment, confirms service is restored, and moves to a monitoring stage. | | 11:49 AM | Vapi marks the incident as resolved. |

# Vapi RCA - US Platform Outage, May 21, 2026 **RCA:** US Platform Outage (Database Connection Exhaustion) **Status:** Resolved **Primary Impact:** Voice calls and API requests failed; the dashboard was unavailable **Date:** May 21, 2026 **Customer-facing systems affected:** Calls, API, Chat, Dashboard, Logs **Severity:** Critical ### Executive Summary On May 21, 2026, the Vapi US platform was unavailable for approximately 4 hours and 7 minutes, beginning at 7:02 AM PT, with service restored by 11:09 AM. Calls began failing at 7:02 AM PT, and by 7:12 AM PT the platform had progressed to a full outage of voice calls and the dashboard. During the window, voice calls failed to connect or complete, API requests returned errors, and the dashboard was inaccessible. Customers served from our EU and AUS regions were not affected. The outage began with a configuration change our database provider applied at 6:44 AM PT to the audit logging module used by our databases. The telemetry/audit logging setting caused Postgres processes to block while writing log output (syslog) at the moment they accepted new connections. Two databases that every call and API request depends on stopped accepting traffic, so the platform could neither authorize requests nor record new calls. Service was restored after the provider disabled the affected logging and restarted the database, and we ramped traffic back in a controlled way to avoid a second failure. We marked the incident resolved at 11:49 AM PT after sustained monitoring confirmed stability. The changes below focus on removing the dependencies that let a database fault become a full outage. ### What You May Have Observed - Inbound and outbound voice calls failing to connect, or ending early - API requests returning server errors (HTTP 5xx) - Inability to access the Vapi dashboard - Scheduled and campaign calls not firing during the window - A brief period of partial recovery mid-incident, where some calls succeeded before failures resumed ### Timeline (PT) - **6:44 AM**: Our database provider applies a configuration change to audit logging. - **7:02 AM**: First monitors fire for API degradation; calls begin failing. - **7:18 AM**: On-call engineer acknowledges the page and begins investigating. - **7:38 AM**: The core infrastructure team jumped into a formal incident. - **7:43 AM**: Status page updated to report degradation. - **7:53 AM**: Status page updated to confirm a full outage of calls and dashboard. - **8:10 AM**: Production database identified as the source; database provider support engaged. - **8:16 AM**: Escalated with the provider for higher urgency. - **8:29 AM**: Status page confirms the production database as the cause. - **9:35 to 10:00 AM**: Brief recovery after a database restart, followed by renewed degradation as traffic resumed. - **10:03 AM**: Provider identifies root cause: database processes stuck writing audit logs while accepting connections, caused by a misconfigured project-wide telemetry setting. - **10:05 AM**: Affected logging disabled and the database endpoint restarted; the database returns to normal. - **10:05 to 11:09 AM**: Traffic ramped back gradually, weekly cluster first (restored 10:38 AM), then daily (restored 11:09 AM). - **11:49 AM**: Incident resolved. ### Root Cause **An audit-logging change exhausted the database connection pool** Vapi’s databases include audit logging. At 6:44 AM PT, our database provider changed where that audit output was written. A misconfiguration in the provider's project-wide telemetry settings caused Postgres processes to block while writing log output at the moment they accepted new connections. Connections accumulated in a waiting state until the pool was exhausted, and the affected databases could no longer accept traffic. **A hard dependency on two databases turned the problem into a full outage** Every API request and call passes through two of these databases: one authorizes the request at our API gateway, and the other r
