[Major] Issues with Downloads, Preview, Box Notes and Box Sign
Postmortem
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 October 29, 2025 between 10:07 PM PST and 11:16 PM PST, some users may have experienced difficulties while working in Box. During this time, errors may have occurred when downloading or previewing content and when using Box Notes.
The issue was caused by a disruption with one of our third-party cloud partners. We resolved the issue by restarting and scaling up the impacted backend services. In addition, we are examining how to improve our resiliency to these scenarios 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
