Caching for deleted keys

Disabling or deleting keys in an external key store can impact data accessibility in AWS services, with key caching durations typically ranging from 5 minutes to 24 hours. However, the exact caching times for services like EC2 and S3 are unspecified in public documentation. It's best to assume that the data may become inaccessible shortly after the key is disabled or deleted.

To avoid potential issues, it's crucial to establish a robust key management strategy. This strategy should include regular key rotation and backups to prevent data loss or service disruption. Proper key management ensures that your data remains secure while maintaining the required level of accessibility.
