Scheduled CoreWeave InfiniBand Network Maintenance - US-EAST-04APlanned Maintenance

Description

CoreWeave will be performing scheduled InfiniBand network maintenance on Tuesday, August 18, 2026, from 11:00 AM ET (3:00 PM UTC) to 1:00 PM ET (5:00 PM UTC) in US-EAST-04A. Location: US-EAST-04A 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 support@coreweave.com.
