Around 04:14 UTC on December 19, 2025, Akamai identified an issue with one Object Storage system in Chicago that caused Lifecycle (LC) processing to fail. As a result, data was not deleted as expected, leading to data buildup and over-quota conditions for some customers.

 The investigation determined that a Ceph version mismatch was the root cause of the LC processing failures. The issue was resolved by performing the required upgrades, and the impact was mitigated by approximately 12:25 UTC on December 24, 2025.

To prevent recurrence, Akamai will review the actions taken as well as the relevant procedures and implement the necessary changes.

This summary provides an overview of our current understanding of the incident given the information available. Our investigation is ongoing, and any information herein is subject to change.
