We recently addressed issues affecting Events and Box Drive. We would like to take the opportunity to further explain these issues and the steps we have taken to prevent recurrence.

‌

Between October 14, 2026 at 3:00 PM PDT and October 15, 2026 at 5:10 AM PDT, some customers may have experienced delayed Events delivery and Box Drive synchronization.

‌

Analysis

The incident was caused by an unexpected workload surge. We remediated the issue by deploying a targeted filter for the workload and adding capacity. During the mitigation, some Events and Drive synchronizations may have been delayed.

‌

Corrective Actions

Box has initiated the following corrective actions:

‌

• Adding monitoring and improved workload filtering tools to respond to future incidents quicker.
• Exploring ways to automatically handle unexpected workload changes across our event processing systems.

‌

We are continuously working to improve Box and want to make sure we are delivering the best product and user experience we can. We hope we have provided some clarity here and we would be happy to answer any questions you may still have regarding this matter.

‌

Sincerely,
The Box Team
