_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 Aug 6, 2026 between 6:42 PM PDT and 6:48 PM PDT and again between 7:27 PM to 7:33 PM PDT, some customers may have experienced intermittent failures affecting login, uploads/downloads, Notes, Box AI, and API access in Box.

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
