Reduced GPU capacity in US-CENTRAL-08A (DH204)
Started:
US-CENTRAL-08
CoreWeave Cloud
CoreWeave Infrastructure
resolved
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.
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...
