mintlify Outage History

Mintlify experienced a search functionality issue where search queries were not returning results, affecting the Display component. The problem was identified and resolved within 58 minutes, with the team continuing to monitor the service afterward.

Mintlify conducted a scheduled database migration on June 4th, 2026 at 8:30pm PST that paused updates for the service. The maintenance was planned for 30-60 minutes but was completed in just 8 minutes with no other service interruptions. Updates resumed normally after the migration was finished.

Mintlify experienced page cache revalidation issues that prevented documentation site updates from being published for 1.7 hours. The problem was caused by rate limiting during an attempted migration, which affected the Updates component. The issue was resolved by stopping the migration, retriggering revalidation for all affected customers, and implementing monitoring while reviewing the migration approach.

Mintlify experienced documentation update failures for sites using AsyncAPI specifications due to a transitive dependency bump that caused parsing failures for valid AsyncAPI specs. The issue affected the Updates component and prevented documentation from being properly updated. The problem was resolved by rolling back the problematic dependency and deploying the fix.

Mintlify experienced a security incident involving their integrations provider Composio, where user credentials for third-party integrations in Slack Agent and Workflows products may have been accessed. The company disabled affected features, revoked all vendor and customer credentials associated with Composio, and directly contacted all potentially impacted customers via email. GitHub and GitLab integrations remained secure as they are handled internally and were never exposed to the compromised vendor.

Mintlify experienced a major service disruption lasting 1.2 hours where search functionality, dashboard access, and content updates were completely unavailable. While existing documentation pages remained accessible for viewing, users could not search content, access the dashboard, or see new updates propagate to the live site. The incident was resolved after active investigation into the root cause.

Mintlify experienced an issue where a small subset of GitHub pushes were not triggering deployments, affecting the Updates component for 1.9 hours. The team identified a bottleneck in webhook processing as the root cause and deployed a mitigation to resolve the problem. The service is now being monitored to ensure the issue does not recur.

The Mintlify Slack app experienced an issue preventing it from creating pull requests, while other AI features and the dashboard remained operational. The incident lasted 1.7 hours before being resolved with a deployed fix after the root cause was identified.

Several Mintlify documentation sites experienced partial outages for 26 minutes, with users reporting missing CSS/JS files and 500 errors preventing pages from loading entirely. The incident was resolved by scaling up internal services and purging caches for affected sites, restoring full functionality without requiring any customer action.

Mintlify experienced a minor security incident due to an upstream security event at their infrastructure provider Vercel. The incident prompted Mintlify to proactively rotate all secrets and credentials and conduct thorough investigations of their audit logs and third-party integrations. After 50.7 hours of monitoring and investigation, no evidence was found that Mintlify or its customers were affected by the security event.
