MongoDB Atlas is the fully managed cloud database service for MongoDB, the world's most popular document database. Atlas hosts over 1.5 million databases across AWS, Google Cloud, and Azure, providing automated scaling, backups, security, and multi-region replication. Developers choose Atlas for its flexible document model, powerful query language, and ability to handle diverse data structures without rigid schemas. Atlas also offers Atlas Search (full-text search), Atlas Vector Search, and Realm mobile sync.
MongoDB Atlas outages vary by underlying cloud provider — an AWS us-east-1 issue may take down Atlas clusters in that region. Common causes include cluster scaling operations that timeout, backup processes consuming excessive I/O, connection storm handling during traffic spikes, and authentication service disruptions at the Atlas control plane level. Atlas Serverless instances may experience cold start issues during low-traffic periods.
When MongoDB Atlas is down, applications lose access to their primary database. Read and write operations fail, causing application errors or crashes. Real-time data features powered by change streams stop delivering updates. Atlas Search queries return errors, breaking search functionality. For applications using Atlas as their sole database, an outage means complete data unavailability until service recovers.
Use this page to check MongoDB Atlas availability. Atlas clusters run on AWS, GCP, or Azure, so outages can be region and provider-specific. Check status.cloud.mongodb.com for the official Atlas status page with per-region health information.
Connection failures can be caused by Atlas outages, IP whitelist restrictions, expired database credentials, or network peering issues. Check that your IP is in the Atlas Network Access list. Verify your connection string is correct and that your cluster hasn't been paused (free-tier M0 clusters pause after 60 days of inactivity).
Atlas replica sets automatically failover to a secondary node when the primary becomes unavailable. For multi-region deployments, Atlas can promote a secondary in a different region. This happens automatically within seconds for most configurations. However, Atlas control plane outages may prevent new cluster management operations.
Atlas is available in 100+ regions across AWS, Google Cloud, and Azure. You can deploy clusters in multiple regions for redundancy. If one region experiences an outage, your application can failover to another region automatically with Atlas multi-region deployments configured.
Use PinusX Uptime Monitor to check your application's endpoints that depend on Atlas. This gives you end-to-end visibility — if Atlas is down and your app returns errors, you'll be alerted within 60 seconds via Slack or email. This complements Atlas's built-in monitoring with independent external verification.
