Between 07:40 and 10:52 UTC on February 12, 2026, some customers experienced issues accessing their Block Storage volumes in the Stockholm region. During this period, storage operations stalled, resulting in a temporary denial of service for affected users. Monitoring detected a complete drop in storage throughput, and impacted customers were unable to access data on their volumes during the impact window.

The incident was traced to a gap in the execution sequence during a recent storage system upgrade, which resulted in the storage environment entering a degraded state. The scenario was documented, however it was not clearly incorporated into the upgrade workflow, as it had not been encountered in previous upgrades.

To mitigate the impact, Akamai initiated recovery actions and restored normal working service. In response, the upgrade process has been updated to include clearer guidance for handling similar situations.

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
