On Sunday, January 8, 2023 from 11:00am EDT to 3:00pm EST, we will be upgrading the Kubernetes orchestration layer of CoreWeave Cloud from 1.20.15 to 1.21.14. This maintenance event is deemed to be a Critical Infrastructure Maintenance under the CoreWeave Terms of Service. While there is no expected interruption to workloads or customer environments, the upgrade of core Kubernetes components carries extra risk.
While we have tested this upgrade extensively to ensure compatibility with our base services, we ask that all CoreWeave Cloud customers assess their deployment and resource configurations to ensure that they will remain compatible with the upgrade. Please refer to the Kubernetes changelog for version 1.21.14 to identify any potential incompatibilities with your environment. For the avoidance of doubt, all changes listed in the 1.21 release log up to and including version 1.21.14 are additive and will be included in the upgrade on CoreWeave Cloud.
CoreWeave will be performing routine network maintenance on Monday, January 23th from 7:00 PM PST to 10:00PM PST (03.00 UTC 01/24 to 06.00 UTC 01/24).
Scope: We will be updating Network configurations during this window
Impact: There may be periods of brief packet-loss towards the internet during the maintenance
This activity is deemed Planned Maintenance under the CoreWeave Terms of Service Maintenance Policy (docs.coreweave.com/resources/terms-of-service/maintenance-policy)
