Authentication failures when running search queries for some clusters
We have identified the root cause of the search query failures and are working on a mitigation for impacted clusters. Clusters with dedicated search nodes are unaffected. Some clusters with colocated search nodes may see search query failures.

What to do next

Verify your own services recovered cleanly. Some upstream outages leave queues or caches in a degraded state, run smoke tests before declaring green internally.
Save the post-mortem. Vendors usually publish a detailed RCA 1-3 days later. We'll add it to this page when it appears.
Watch the provider going forward. Follow MongoDB Atlas's status feed →

GlobalOutageMap aggregates publicly reported signals. We never claim authoritative status, always cross-check the provider's official channel before making business decisions.
