Backend fabric performance degradation in US-CENTRAL-08A

Hello,

We are investigating degraded performance on the backend GPU interconnect fabric in US-CENTRAL-08A. Multi-node GPU workloads may see reduced bandwidth or increased latency. Our engineering team is actively working on this. We will provide updates as the situation develops.

If you have any questions, please reach out to our support team at support@coreweave.com or raise an inquiry in your dedicated Slack channel.

Thank You,
