_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 August 24, 2026 between 10:28 AM PDT and 10:35 AM PDT, some customers may have experienced failures signing in and intermittent inability to access files and other core Box features. The disruption was caused by a traffic increase at our edge load-balancers that delayed requests to back-end services. Error rates returned to normal after the traffic spike subsided and services recovered. We are reviewing our load-balancing and client-connection practices and working with our cloud provider to reduce the likelihood of recurrence. 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
