A maintenance event is scheduled to occur between 17:00 UTC and 18:00 UTC on December 6, 2025. You may encounter the following impact during this maintenance, which should not exceed 5 minutes: - Workspace authentication requests may fail or timeout. - Cluster start/resize/termination requests may fail or time out. - Jobs relying on cluster start/resize/termination may not execute. - Jobs submitted through APIs/Schedulers may not execute. - UI and Databricks SQL queries may time out. - Users may experience failures launching Databricks SQL Serverless Warehouses. - Users may not be able to access UC APIs. Currently running jobs may be interrupted.

Description

Databricks is migrating the Hive Metastore (HMS) infrastructure to a new platform. As part of this migration, the HMS backend databases will move to servers with new IP addresses and subnets. If you currently reference Hive Metastore IP addresses directly in user-defined routes or firewalls, you must update your configuration before the maintenance window. Failure to update these rules will result in Hive Metastore access failures and service outages (e.g., job failures, cluster start failures). Maintenance Window The migration will occur between 18:00 UTC and 20:00 UTC on December 08, 2025. Each region will experience a brief service interruption of approximately 5 minutes during this window. Action Required (must be completed prior to December 08, 2025) If your environment uses hard-coded Hive Metastore IP addresses: 1. Recommended:
 Update your user-defined routes or firewall rules (https://learn.microsoft.com/en-us/azure/databricks/security/network/classic/udr#azure-service-tags) to use the Azure SQL service tag instead of static HMS IP addresses. This ensures future IP changes do not cause outages.
 2. If your security policy does not allow service tags:
 Add the reserved IP ranges (https://community.databricks.com/t5/product-platform-updates/ip-cidr-for-azure-databricks-hive-metastore/ba-p/133401) for Hive Metastore to your routing or firewall rules.
If supported, you may also allow the HMS FQDNs provided in the same documentation.
 Customers who already allow Azure service tags or FQDN-based rules do not need to take further action and will not experience disruption to running jobs. These actions must be completed by December 08, 2025. If the maintenance is rescheduled, the same configuration changes will still be required prior to the revised window to prevent service disruption.
