Scheduled Service Change: AWS Resource Explorer Configuration to be Standardized

Event:
2026-02-15 08:00:00
Expected Duration:
2026-02-16 20:00:00
Status:
Closed
Brief Description:
On February 15 and 16, 2026 a standardized Resource Explorer configuration will be deployed to all Cornell AWS accounts. This configuration will create Resource Explorer indexes in all active regions and create an aggregator index in us-east-1.
User Impact:

Full Description:
On February 15-16, 2026 a standardized Resource Explorer configuration will be deployed to all Cornell AWS accounts. This configuration will create Resource Explorer indexes in all active regions and create an aggregator index in us-east-1. 

This new configuration will replace any customer-deployed Resource Explorer configuration. No customer action is required but Resource Explorer degradation is expected during this change. 

  • Cornell AWS accounts without existing aggregator indexes may experience degraded Resource Explorer searches in the period between existing index deletion and when new indexes are fully computed. 
  • Cornell AWS accounts with existing aggregator indexes will have those indexes removed early in this 36-hour change implementation period. New aggregator indexes will be created 24 hours after the previous aggregator index was deleted. This timing is required by a 24-hour waiting period enforced by AWS for such changes. During this waiting period, cross-region searches will not be available. Once the new aggregator index is created, Resource Explorer searches still may be incomplete while new indexes are fully computed.
