## Updates from CoreWeave
### 2026-10-23 16:51 UTC: resolved
October 15, 2026 7:16PM UTC 
 Scheduled - CoreWeave will perform scheduled power infrastructure maintenance in EU-SOUTH-03 region between October 21, 2026 at 06:00 UTC and October 22, 2026 at 08:00 UTC. Work will occur in two separate maintenance periods: October 21 from 06:00–16:00 UTC and October 22 from 06:00–08:00 UTC. 
Location:
EU-SOUTH-03
The work will test backup power systems to verify they can maintain power during an interruption to the electricity supply from the utility grid. During testing, backup generators will supply power to the affected systems before the utility supply is restored. Utility power can also be restored during the test if needed. 
Impact:
No impact to compute, storage, or network availability is expected, and no customer action is required. Power redundancy will be temporarily reduced while the utility supply is disconnected for testing. Customer workloads are expected to remain available throughout the maintenance. 
We will actively monitor systems throughout the maintenance. If you have questions or require assistance, please contact our support team at support@coreweave.com.
This activity is deemed Planned Maintenance under the \[CoreWeave Terms of Service Maintenance Policy\](https://docs.coreweave.com/policies/terms-of-service/maintenance-policy).
