Is CoreWeave down?

We’re currently experiencing a degradation in the CoreWeave Object Storage Service in US-EAST-04, which may result in intermittent request failures for some customers. Our team has identified the root cause and is actively working on a fix to restore full functionality as quickly as possible. If you have any questions or concerns in the meantime, please don’t hesitate to reach out to us at [email protected]

Hello, We have mitigated the issue affecting CoreWeave Object Storage in US-EAST-04. Requests are completing normally again, and we are finishing a configuration fix across the affected storage systems while we monitor for stability. If you continue to see failed or slow requests in this region, please contact [email protected]. Thank you for your patience, CoreWeave Support

Hello, We are actively investigating a facility power event in US-EAST-15A following the loss of both utility power feeds at the site. Customers in this region may experience compute unavailability, job interruptions, , Inference disruptions and degraded or unavailable Object Storage. Our engineering and facilities teams are actively working to restore stable power and cooling. Impact may continue or widen until site conditions stabilize. If you are impacted or have questions, please contact [email protected]. We apologize for the disruption and thank you for your patience. Thank you, CoreWeave Support

The disruption has been traced to a tripped main feed from the local utility provider, who is actively troubleshooting on site. The facility is running on backup generator power, cooling has been restored, and room temperatures are returning to normal. When utility power gets restored, we will begin bringing systems back online in stages, prioritizing restoring customer capacity. A subset of racks sustained a cooling related hardware issue during the event and require servicing before they can be powered back on; we currently estimate these will be restored by Friday morning. We expect more information on the utility power timeline within the next hour and will post more updates

Power has been restored and node recovery is underway. Nodes are being brought back online in phases, starting with air cooled systems; B200 (liquid cooled) nodes will follow once that first phase completes. We expect full recovery by Morning time due to the subset of racks which sustained a cooling issue during the event and require servicing before they can be powered back on. We'll share more updates as more nodes return to service.

Most capacity in US-EAST-15A has been restored following the facility power event. Power is stable, and we are not expecting a repeat of the utility disruption. A subset of racks still requires follow-on facility work (including coolant servicing) before they can be safely returned to service. Recovered capacity remains available for use while that work continues. We will keep this incident in Monitoring until remaining facility recovery is complete, and will post another update when that work wraps up or if the situation changes. Thank you, CoreWeave Support

We are investigating a renewed cooling disruption at the US-EAST-15A facility, with additional racks shutting down and customer impact observed. Customers in this region may experience compute unavailability, job interruptions, and inference disruptions. Our engineering and facilities teams are working with the facility provider to determine the cause and restore stable cooling. Impact may continue or widen until site conditions stabilize. If you are impacted or have questions, please contact [email protected]. We apologize for the renewed disruption and thank you for your patience. Thank you, CoreWeave Support

Our facility provider has confirmed a renewed loss of utility power at US-EAST-15A, and the site is currently running on backup generators. The utility provider is investigating the power loss, while the facility's cooling specialists are on site investigating the cooling disruption. We apologize for the continued disruption and thank you for your patience. If you are impacted or need assistance, please contact [email protected]. Thank you, CoreWeave Support

Power has been restored at US-EAST-15A, and we're working to stabilize the site. Most affected nodes are back in service, and we're bringing the remaining nodes back online. We'll continue to monitor the site and share updates as recovery progresses.
