CoreWeave Outage History

We are investigating an issue that is causing errors when creating new Dedicated Inference deployments or editing existing ones. Deployments that are already running are not affected and continue to serve traffic normally.

Hello, We are currently investigating an issue affecting CoreWeave Cloud authentication (OIDC) services. Customers may experience issues accessing CAIOS, authenticating through OIDC, or obtaining credentials for CAIOS workloads. Our team is actively working with the highest priority level to restore full functionality as quickly as possible. We apologise for any inconvenience and appreciate your patience while we work to resolve the issue. — CoreWeave Support

We're investigating degraded performance with metrics in US-EAST. Querying US-EAST metrics in Grafana may be slow or return intermittent errors. Metric ingestion is degraded, but no metric data is being lost, and customer workloads are not affected. We'll provide updates as we remediate.

Hello, We are actively investigating an issue that is impacting our storage services in US-EAST-13A. As the situation evolves, we will continue to update our customers on the matter. If you have any questions, we encourage you to reach out to support by email: [email protected] We apologize for any inconvenience this may cause and thank you for your patience while we work to resolve the matter in a timely manner. Thank you, CoreWeave Support

We are investigating elevated error rates and increased latency for Object Storage in the US-WEST-01A region. Requests to this region may intermittently return HTTP 503 responses or take longer than usual to complete. Our engineering team is actively engaged and working to identify the root cause.

We are investigating renewed elevated error rates and increased latency for object storage in US-WEST-01A. A change applied earlier today improved service for a period, but the degradation has returned and our engineering team is actively engaged and working to identify the root cause. Clients may see intermittent 503 responses.

We are investigating a loss of production GPU capacity affecting a subset (19) of GB300 racks in DH204. Affected nodes have intermittently gone unhealthy and been evicted; a number have been taken out of production for recovery. Affected: GB300 compute, DH204 (clusters msl-cw-use2-1, msl-cw-use2-2) Current impact: Several racks are below the 16-node threshold for a full NVL64 domain, so multi-node jobs targeting those racks may fail to place or may be interrupted. Capacity in other datahalls and regions is unaffected. The first node losses were observed at approximately 2026-08-19 19:00 UTC. Fleet Operations has been recovering nodes by reboot since then, and additional engineering teams were engaged at 16:30 UTC today. We will keep you posted on further details as we progress. Thank you for your patience and cooperation while we are investigating.

Beginning at 22:51 UTC on 13 August 2026, we identified a network connectivity issue affecting internal service communication within the EU-SOUTH-03B availability zone. Customers in this availability zone may experience intermittent errors or delays when performing cluster control-plane operations, such as Kubernetes API requests. Running workloads and compute nodes are not currently showing impact. Our networking teams are actively engaged and investigating. Other availability zones and regions are unaffected.

Hello, We are actively investigating a storage issue that may be impacting our storage services in US-EAST-02A. As the situation evolves, we will continue to update our customers on the matter.

We are investigating a networking hardware issue in US-EAST-04A affecting connectivity for a subset of nodes. Out of an abundance of caution, impacted nodes have been temporarily removed from service while our engineers work to restore connectivity. Customers may see a small number of nodes become unavailable or unschedulable during this time.

We are investigating an infrastucture degradation in the US-EAST-04A region that may result in loss of connectivity to the cluster. As the situation evolves, we will continue to provide updates. If you have any questions, please contact [email protected]. We apologize for any inconvenience this may cause and appreciate your patience while we work to resolve the issue as quickly as possible.

We are currently investigating an elevated rate of failed requests to CoreWeave AI Object Storage in the US-EAST-06 region.

We're currently investigating an issue that is preventing metrics and dashboards from loading for resources in our US-EAST regions. Customers may be unable to view cluster and node metrics in Grafana, and monitoring queries for US-EAST resources are returning errors. This is limited to metrics visibility only - It does not affect the health, availability, or performance of your running workloads, clusters, or nodes - compute continues to operate normally. Other regions (US-WEST and US-CENTRAL) are unaffected and their dashboards remain fully available. Our engineers are actively investigating and working to restore metrics access as quickly as possible. We apologize for the disruption and appreciate your patience.

Hello , We're investigating an issue affecting metrics and logs in EU-NORTH. Customers with workloads in EU-NORTH-04 and EU-NORTH-05 may see missing metrics and logs. Compute and running workloads are not affected. Our team is actively working on to remediate the issue. We will keep you posted as we progress. We apologise for any inconvenienve and thank you for your patience! Thanks, CoreWeave Support
