    We are investigating an issue with Google Cloud Platform (GCP) capacity that is affecting some MongoDB Atlas customers across multiple GCP regions and geographies. We expect the scope of this issue to continue to expand as our investigation progresses. It currently includes, but is not limited to, multiple GCP regions across North America, Europe, and Asia Pacific/Australia, as well as M50 and S70L instance types. Customers may experience errors or delays when creating or modifying Atlas clusters, particularly deployments with search nodes. Some customers may also see host-down alerts while this issue is ongoing. MongoDB is working with GCP to understand the scope of the issue and restore capacity. Customers encountering provisioning issues may retry later or consider using a different GCP region, cloud provider, or instance size. If you are experiencing a time-sensitive production impact, please contact MongoDB Support through the Support Portal or the in-product support chat.

    Azure is rolling out a mitigation for the ongoing networking incident affecting the West US region, and we are seeing signs of recovery. Some Atlas clusters hosted in Azure West US may continue to experience intermittent connectivity issues, including failures connecting to clusters, issues with communication between cluster nodes, nodes appearing down, and delays to cluster modifications. We are monitoring recovery closely and will provide additional updates as more information becomes available.

  1. 16:14 UTC · identified
    Due to an ongoing incident with AWS's billing data, MongoDB Atlas and Atlas for Government will not be updating AWS network or backup consumption data over this weekend, 2026-07-17 through 2026-07-20. The products themselves will remain fully available. When the upstream issue has been resolved, we intend to display and bill for the correct amounts. Charges will have usage dates that correctly express the usage, but will have the billed date of when this is corrected. Cluster and backup health are unaffected. Other cloud providers' billing data is unaffected. You can follow the upstream incident at https://health.aws.amazon.com/health/status

    The upstream issue has been corrected. After approximately 0400 UTC on 2026-07-21, most, if not all, of the updated backup and network consumption on AWS will be reflected in MongoDB Atlas and Atlas for Government. Thank you for your patience during this incident.
