Scheduled CoreWeave InfiniBand Network Maintenance - US-WEST-09B — August 19, 2026 5:57PM UTC Scheduled - CoreWeave will be performing scheduled InfiniBand network maintenance on Thursday, August 20, 2026, from 11:00 AM ET (3:00 PM UTC) to 2:00 PM ET (6:00 PM UTC) in US-WEST-09B. Location: US-WEST-09B. During this window, our network engineering team will upgrade the InfiniBand fabric. The components are upgraded one at a time so that InfiniBand fabric management remains available throughout the maintenance. Impact: We anticipate minimal impact. InfiniBand connectivity within this site should remain available for the duration of the window; however, during the failover between redundant components there is a small chance of a brief interruption to workloads using the affected fabric. 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]. This activity is deemed Planned Maintenance under the CoreWeave Terms of Service Maintenance Policy ( https://docs.coreweave.com/policies/terms-of-service/maintenance-policy ) August 20, 2026 3:00PM UTC Active - This maintenance has started. August 20, 2026 6:00PM UTC Completed - This maintenance is complete.

Reduced GPU capacity in US-CENTRAL-08A (DH204) — August 20, 2026 5:12PM UTC Investigating - 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 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.
