[Critical] Issue with Downloads

Final update

We recently addressed issues affecting Downloads \(including ZIP downloads\) in Box. We would like to take the opportunity to further explain these issues and the steps we have taken to keep them from happening in the future. Between August 24, 2026 at 11:25 PM PDT and August 25, 2026 at 12:05 AM PDT, some Box Zones Japan users may have had a degraded download experience. The disruption was caused by an unusual traffic pattern that placed unexpected strain on capacity in the region. Once the impact was identified we restored service by directing download traffic to another region and adding capacity. Downloads returned to normal by 12:05 AM PDT. Once confirming that the issue had been addressed, we returned traffic to the original region. Of note, even during the period of temporary traffic redirection, all Box Zones customer content was stored in the correct Box Zones region. # Analysis This incident highlighted opportunities to make our systems more resilient to unusual traffic patterns, to strengthen regional capacity safeguards, and to further improve monitoring so that conditions like these are detected and addressed before affecting customers. # Corrective Actions Box has in
