Scheduled Critical CoreWeave Cloud Maintenance - All Regions — October 23, 2026 9:44PM UTC Scheduled - CoreWeave will be performing critical maintenance on Monday, October 26, 2026 from 20:30 UTC to 21:30 UTC that will affect the CoreWeave VPC API. During this window, we will renew a security certificate used by this service. Location: All regions Impact: During this window, requests to get or update a VPC may intermittently fail for up to 10 minutes. Retrying the request should resolve this. Creating and listing VPCs are not affected. Running workloads, nodes, storage, and networking are not affected, and no data loss is expected. No action is required on your side. We will be actively monitoring the situation during this time. We appreciate your patience and understanding. If you have any further questions or require assistance, please don't hesitate to reach out to our support team at [email protected] October 26, 2026 8:36PM UTC Active - The scheduled critical maintenance on the CoreWeave VPC API has started. We are now renewing a security certificate used by this service. Until the work is complete, requests to get or update a VPC may intermittently fail for up to 10 minutes; retrying the request should resolve this. Creating and listing VPCs, running workloads, nodes, storage, and networking are not affected. We will post an update when the maintenance is complete. October 26, 2026 9:26PM UTC Completed - The scheduled critical maintenance on the CoreWeave VPC API is complete. The security certificate has been renewed, and the service is operating normally. Some requests to get or update a VPC may have failed intermittently during the maintenance; these requests can be retried now. No further action is required on your side. If you have any questions, please contact our support team at [email protected].

Scheduled Network Maintenance: Switch Firmware Update (Multiple Availability Zones) — October 13, 2026 8:55PM UTC Scheduled - Details: CoreWeave will be performing network maintenance from Monday, October 19, 2026 at 12:00 UTC to Friday, October 23, 2026 at 00:00 UTC. Work runs during daytime hours each day in the window, 12:00 UTC to 00:00 UTC. We are applying a vendor-recommended firmware update to the boot drives of network switches in the following availability zones: US-CENTRAL-09A, US-CENTRAL-08A, US-EAST-04B, US-CENTRAL-10A, US-EAST-12A, US-CENTRAL-08B This update resolves a known issue that can cause a switch to become unresponsive, and it improves overall network reliability. Impact: No impact is expected. The update is applied live, without switch reboots or node drains, and running workloads can continue without interruption. In rare cases, a switch may need a brief restart after the update. Where this affects backend (GPU-to-GPU) network switches, a small number of nodes may temporarily lose part of their backend network bandwidth until the restart completes, which may affect multi-node jobs running on those nodes. Engineers and on-site technicians will be monitoring throughout the window, and affected customers will be contacted directly. No customer action is required. October 19, 2026 4:21AM UTC Active - Scheduled maintenance October 22, 2026 10:48PM UTC Active - This maintenance has been extended through Friday, October 23. October 26, 2026 4:51PM UTC Completed - Maintenance is done

Facility power incident impacting services in US-EAST-15A — October 22, 2026 9:32PM UTC Identified - 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 October 23, 2026 12:05AM UTC Monitoring - 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 October 23, 2026 3:06AM UTC Monitoring - 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. October 23, 2026 9:05PM UTC Monitoring - 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 October 25, 2026 12:43AM UTC Investigating - 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 October 25, 2026 2:06AM UTC Investigating - 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 October 26, 2026 4:27AM UTC Monitoring - 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.
