[Critical] Issues with Multiple Box Services

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 February 24th, 2026 between 6:11 AM PST and 6:40 AM PST, some users may have experienced difficulties while while attempting to log into Box. Users already logged into Box were not impacted by this issue. The issue occurred due to a recent configuration change related to device security that prevented users from logging in to Box. We were able to resolve the issue by quickly reverting the change. We are also working to improve our release strategy and testing processes to prevent similar issues from occurring in the future.

‌

We are conducting a full engineering postmortem and 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
