Scheduled Service Change - AWS Resource Explorer Configuration to be Standardized

<div>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.&nbsp;<br><br>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.&nbsp;<br><br></div><ul><li>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.&nbsp;</li><li>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.&nbsp;</li></ul><div>See the list of <a href="https://confluence.cornell.edu/x/mYCaJQ">affected AWS accounts on Confluence</a> (login required).</div>
