Major October 22, 2026 Facility power incident impacting services in US-EAST-15A 11d 8h CoreWeave Infrastructure, CoreWeave Object Storage, CoreWeave Services, CoreWeave Inference and 4 more

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
- monitoring Oct 23, 2026, 12:05 AM UTC
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
- monitoring Oct 23, 2026, 03:06 AM UTC
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.
- monitoring Oct 23, 2026, 09:05 PM UTC
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
- investigating Oct 25, 2026, 12:43 AM UTC
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
- investigating Oct 25, 2026, 02:06 AM UTC
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
- monitoring Oct 26, 2026, 04:27 AM UTC
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.
- resolved Nov 03, 2026, 05:43 AM UTC
US-EAST-15A experienced a utility power loss (both feeders) that put the site on generator and caused emergency power-off on some racks. Power was restored, confirmed stable since Oct 25 05:28 UTC, and all affected capacity is back in service.

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.

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.

Between 22:51 UTC on 13 August and 00:38 UTC on 14 August 2026, customers with resources in the EU-SOUTH-03B availability zone may have experienced intermittent errors performing cluster control-plane operations, degraded cluster access, and brief periods where nodes reported as unavailable. The cause was a hardware fault affecting network links within the availability zone. Our network engineering team removed the affected links from service, and connectivity has been stable since 00:38 UTC. Node capacity was not lost during this event, and no other availability zones or regions were affected. This incident is now resolved.

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.

Metrics and dashboards for our US-EAST region have been restored, and monitoring queries are returning results normally again. Our engineers have applied a fix and are continuing to monitor closely to confirm full stability. As noted earlier, this issue was limited to metrics visibility and did not affect the health, availability, or performance of running workloads, clusters, or nodes. If you're still seeing gaps or errors when loading US-EAST metrics, please let us know. We'll post a final update once we've confirmed the region is fully stable. Thank you for your patience during the disruption.
