Update timeline
- investigating Mar 25, 2026, 09:31 PM UTC
We are currently investigating intermittent spikes of HTTP 503 errors affecting Atlas control plane operations performed via the Atlas Admin API and automation tooling such as Terraform. Impacted requests typically fail for a short period and succeed on retry. Atlas database connectivity and data plane operations remain healthy. Our engineering teams are working to resolve the issue with high urgency and to prevent recurrence. Customers encountering 503 responses are advised to retry failed Admin API and Terraform operations with appropriate retry logic and backoff while we continue our investigation.
