MongoDB Cloud Status

Identified: According to AWS, two Availability Zones in me-central-1 (UAE) and one Availability Zone in me-south-1 (Bahrain) continue to experience impairments.

We continue to assist customers in their chosen remediation path to the extent possible. We encourage customers running workloads in the Middle East to consider alternate Atlas regions, such as those in North America, Europe, or Asia Pacific, as appropriate for your latency and data residency requirements. Customers may consider extending their backup snapshot expirations in me-central-1 as needed.

We expect our guidance to remain unchanged for the immediate future. We will move to a weekly status post update cadence, and provide another update by March 18 at 16:00 UTC, or sooner if new information becomes available.

Identified: CURRENT IMPACT

According to AWS, two Availability Zones in me-central-1 (UAE) and one Availability Zone in me-south-1 (Bahrain) continue to experience impairments. The latest information from AWS is available at: https://health.aws.amazon.com/health/status.

AWS is currently experiencing infrastructure impairments in two Middle East regions:

• ME-CENTRAL-1 (Middle East – Central): Two Availability Zones are impaired due to an underlying power and facilities issue. This is resulting in elevated error rates and latency across several AWS services. Recovery is currently expected to take at least a day, per AWS.
• ME-SOUTH-1 (Middle East – Bahrain): A single Availability Zone is experiencing a localized power issue. While some services have shifted traffic to unaffected Availability Zones, resources deployed in the impacted zone may continue to experience availability issues, elevated error rates, or extended recovery timelines. Recovery is also currently expected to take at least a day.

Because MongoDB Atlas runs on AWS infrastructure, Atlas clusters deployed in the affected Availability Zones may be unavailable or experience operational impact, and certain Atlas management operations (including the Atlas UI, API, and CLI) may show increased error rates during this time.

The impact of these events depends on your Atlas cluster topology and configuration:

• Customers using multi–region deployments, global clusters, or replicas located in unaffected Availability Zones or regions may see little to no impact.
• Customers with clusters or workloads primarily located in the affected Availability Zones may experience reduced availability or degraded performance.
• Clusters deployed entirely in unaffected Availability Zones or outside the impacted regions are operating normally.

AVAILABLE OPTIONS

Depending on your application requirements and cluster configuration, you may consider the following options:

1. Move the cluster to another region that is not impacted.
2. Add electable nodes in another region, which can enable the cluster to establish a minimum viable topology and restore database operations.
3. Take no action and wait for the affected Availability Zones to be fully recovered.

Identified: According to AWS, two Availability Zones in me-central-1 (UAE) and one Availability Zone in me-south-1 (Bahrain) continue to experience outages. The latest information from AWS is available at: https://health.aws.amazon.com/health/status.

CURRENT IMPACT Atlas clusters deployed only in me-central-1 may be fully unavailable.

For clusters operating solely in me-central-1, backup operations in this region are impaired.

Clusters and backups should remain operational in me-south-1 at this time. Clusters in me-south-1 may be running at reduced capacity due to zonal constraints.

AWS has indicated an extended resolution timeline for service in the impacted Regions and Availability Zones.

RECOMMENDED CUSTOMER ACTIONS If you have a multi-region configuration that includes a healthy secondary region, we recommend routing application traffic to that secondary region.

If you have clusters in me-south-1 taking backups, we recommend enabling "Additional Snapshot Copies Policy" to a different region.

If you have time-sensitive production changes or operations that are blocked and need urgent assistance, please contact MongoDB Support via the Support Portal, Support Chat or in-product support.

WHAT WE ARE DOING We recognize the severity of this situation and the impact it may have on your workloads. The situation continues to evolve, and we are closely monitoring AWS status and regional health signals. We are validating Atlas behavior across affected and unaffected regions, and working to mitigate customer impact where possible.

We will provide further updates as circumstances continue to change.

Identified: Update: We are continuing to monitor an ongoing issue in AWS me-central-1 (United Arab Emirates) caused by an underlying AWS infrastructure disruption isolated to a single Availability Zone. Please visit the AWS Health Dashboard for detailed information on the Availability Zone outage (https://health.aws.amazon.com/health/status).

If you have time-sensitive changes that are blocked and need urgent assistance, please contact MongoDB Support.

Identified: Update: One or more instances backing MongoDB Atlas clusters in the AWS ME-CENTRAL-1 (United Arab Emirates) region may have been temporarily unavailable due to an underlying AWS issue in a single Availability Zone . According to AWS, a localized power issue in this Availability Zone has affected connectivity and power for some APIs and instances, and may have caused increased errors, latency, or unavailability for certain workloads. For the latest information from AWS, see the AWS Health Dashboard.

We continue to closely monitor Atlas deployments in ME-CENTRAL-1 and will provide additional updates if we observe any further impact to Atlas customers.

Identified: Impact: Some Atlas customers with deployments in the AWS me-central-1 (United Arab Emirates) region may experience delays in cluster operations (for example, creating, scaling, or modifying clusters and infrastructure-level maintenance tasks).

Root cause: AWS is reporting connectivity and power issues affecting APIs and instances in a single Availability Zone in the me-central-1 Region, which can cause increased errors and latency for some AWS services and workflows. For the latest details from AWS, see the AWS Health Dashboard.

What you might see:

• Cluster create/scale/modify operations remaining in a pending or in-progress state longer than usual
• Slower completion of some maintenance and infrastructure operations in the affected region

Our actions:

• Monitoring the AWS incident and Atlas fleet behavior in me-central-1

Customer action: No action is required at this time. We expect delayed operations to complete as AWS resolves the underlying issue. If you have time-sensitive changes that are blocked and need urgent assistance, please contact MongoDB Support.

Next update: We will provide updates on this page as AWS progresses mitigation or if we observe any change in impact to Atlas customers.

Identified: Azure has an active service issue for virtual machines in East US 2. According to their service health page, "customers using Virtual Machines in East US 2 may have encountered errors when performing service management operations - such as create, update, scale, or start - for resources in this region. [...] During peak impact, an unexpected surge in usage caused backend Virtual Machine components to reach operational limits, resulting in deployment failures for some VMs. We are actively mitigating through load balancing and resource reclamation. Capacity constraints for affected SKUs persist, and our teams continue working to restore normal levels."

We are actively engaging with Azure support.

Investigating: We are experiencing high failure rates when provisioning clusters in Azure Virginia-East2 (eastus2). Please note that cluster creation in this region will likely experience delays until the issue is resolved.

Resolved: At approximately 10:30 AM CT, we identified an issue affecting stream processing within the AWS US-EAST-1 region. As of now, normal operations have resumed. We have initiated a full investigation to determine the root cause and prevent future recurrence.

Resolved: This incident has been resolved.

Monitoring: A fix has been implemented and we are monitoring the results.

Identified: The issue has been identified and a fix is being implemented.

Investigating: Atlas cluster snapshots are failing. We are actively investigating.
