[Minor] Issue affecting Logins

Notice and disclaimer: Box is providing this preliminary information subject to further review and analysis. To the best of our knowledge, this is the current state and we may update as more information is confirmed.

On March 9th 2026, between 3:46 PM PST and 4:32 PM PST, some users may have experienced difficulties while while attempting to log in to Box. Users already logged to Box were not impacted by this issue. The issue occurred due to a overloading and insufficient resources assigned to one of the services used during login process, responsible for ensuring maximum device security of users using Box. The issue was resolved by assigning more resources to the service, sufficient for current and future traffic.

‌

We are conducting a full engineering postmortem to identify gaps in our processes that allowed the service to experience excessive load without more resources being assigned in advance automatically. Our overview is subject to change with further analysis and findings, In the event our continuing investigation yields further substantive findings, we may publish additional analysis after the conclusion of the full engineering postmortem.

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
