Incident Report for Box

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 9:00 AM PST and 12:30 PM PST on November 6, 2023, users may have experienced latency and difficulty logging into Box. During this time, some impacted users may have experienced authentication issues or difficulty logging in through web and SSO. This occurred as a result of an enterprise calling one of our services at a higher than expected rate. We were able to resolve the issue by temporarily rate limiting requests to the impacted service.

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.
