October 15, 2026 3:19AM UTC Scheduled - Details: CoreWeave will perform scheduled power infrastructure maintenance in CA-East-01A between 26 October 2026 at 11:30 UTC and 29 October 2026 at 01:00 UTC. Work will occur in separate maintenance periods within this overall window. Location: CA-East-01A Scope: Install permanent power quality meters and branch circuit monitoring, and complete associated corrective work on Optistax power distribution unit 11C and 11D. Each unit will be isolated individually for up to two days, including overnight isolation where required. Power will be restored and equipment validated before work begins on the next unit. Impact: No customer service interruption or disruption to CDU operation is expected. Equipment supplied by the unit under maintenance will temporarily operate on its remaining redundant power sources. Power redundancy will be reduced during each isolation period and restored after that unit’s work is complete. 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). October 26, 2026 11:30AM UTC Active - Scheduled Power Infrastructure Maintenance has Started. October 29, 2026 1:00AM UTC Completed - Scheduled Power Infrastructure Maintenance has Ended.
