Box Hubs Shared Links Restored After Brief Outage

_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._ Between August 27, 2026 at 11:18 PM PDT and August 28, 2026 at 2:48 AM PDT some customers may have been unable to access Box Hubs using shared links. Other Box functionality, such as file and folder access, was not broadly affected. The issue occurred as a result of a recent code change in our ongoing effort to improve performance. We were able to resolve the issue by rolling back the change so traffic returned to the previous behavior. We are conducting a full engineering postmortem, including a review of our deployment and configuration practices, to reduce the chance of similar issues in the future. 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
