## Timeline of updates

- **unknown** : We have removed the previously communicated deadline to update VNet subnet IDs (BCR-1955) in the Azure - East US 2 (Virginia) and Azure - West US 2 (Washington) regions. Services will remain available, and no immediate action is required. What happened? In May 2025, we announced a future update to the VNet subnet IDs in the affected Azure regions. The update was implemented on August 14, 2025. Based on customer feedback, we extended the timeline on August 18, 2025. After further review, we are removing the deadline altogether. Customers will only need to take action if contacted directly by Snowflake. How will this affect my service? There is no expected service impact at this time. If a migration becomes necessary for your account, Snowflake will notify you with specific instructions and support to complete the change.

_From the vendor’s published history: only the final update text is available for incidents before Rewindex began polling this page._
