Reported components: Coreweave Network. Reported locations: US-CENTRAL-08A, US-CENTRAL-10A, US-EAST-04, US-EAST-12A, US-CENTRAL-09A. 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: CA-EAST-01A, EU-NORTH-04A, EU-NORTH-05A, EU-SOUTH-03B, EU-SOUTH-04A, US-CENTRAL-01A, US-CENTRAL-06A, US-CENTRAL-07A, US-CENTRAL-08A, US-CENTRAL-08B, US-CENTRAL-09A, US-CENTRAL-10A, US-CENTRAL-11A, US-EAST-04A, US-EAST-04B, US-EAST-08A, US-EAST-11A, US-EAST-12A, US-EAST-13A, US-EAST-14A, US-EAST-15A, US-WEST-01A, US-WEST-04A, US-WEST-10A 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.
