# Root Cause Analysis: Encoding Failures on AWS ### Summary On **September 4, 2025**, between **06:31 AM and 08:10 AM CEST**, encoding jobs running on AWS failed due to an issue accessing our S3 storage. ### Root Cause The incident was caused by an error during a routine S3 key rotation. The old access key was deleted before the new key was in use, which temporarily prevented our encoding service from accessing storage. ### Impact * Only encoding jobs running on **AWS** were affected. * Encodings on other cloud providers and all other Bitmovin services were **not impacted**. ### Resolution The configuration was corrected at **08:10 AM CEST**, restoring access to S3\. Encoding operations on AWS recovered immediately and have been stable since. ### Preventive Measures To prevent this from happening again, we are: * Updating our key rotation procedure to ensure keys are not deleted prematurely. * Automating the key rotation process to reduce the chance of operator error..
