[Minor] Issue affecting Logins

We recently addressed an issue affecting logins to Box. We would like to take the opportunity to further explain this issue and the steps we have taken to keep it from happening in the future.

Between 4:46 PM PDT and 5:32 PM PDT on March 9, 2026, some users may have experienced difficulties logging in to Box leading to disruptions when using some Box features. This issue occurred when a service involved in the login process did not have sufficient resources to handle an uneven spike in traffic, which caused a portion of login-related requests to time out. We resolved this by increasing resources for the affected service and expanding its capacity. We also took additional steps to reduce the likelihood that this type of issue could affect the login experience in the future.

Analysis

The incident surfaced opportunities to further refine how we size and distribute capacity across services that support login-related traffic. It also underscored the value of strengthening earlier detection of traffic imbalances and simplifying dependencies within critical login flows.

Corrective Actions

Box has initiated the following corrective actions:

• Strengthen resource allocation and scaling: We are tuning resource allocation and scaling behavior so services can better absorb unusual traffic patterns without degradation.
• Improve traffic distribution and monitoring: We are refining how traffic is distributed across service instances and strengthening monitoring so we can identify and address unhealthy capacity patterns sooner.
• Reduce login path dependencies: We are simplifying the login flow so fewer background checks are required for most users, reducing the potential impact of issues in supporting services.

‌

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
