  4. Resolved

    _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 June 17th 2026 between 12:06pm PST and 12:39pm PST, some users may have experienced difficulties while working in Box. During this time, some customers were unable to browse folders in the web application. The issue occurred because folder browsing traffic was directed to a new implementation, as part of an ongoing effort to improve performance and stability. We were able to resolve the issue through targeted traffic adjustments and capacity mitigations. We are improving our deployment, capacity, and observability practices to prevent recurrence and detect future issues more quickly. 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
