4. postmortemApr 10, 2026, 4:36 PM UTC

   On April 2, 2026 between 8:19 PM PDT and 11:56 PM PDT, some users may have experienced difficulties while working in Box. During this time, Box Sign users might have experienced errors while creating new signature requests, accessing existing signature requests, or attempting ~~been unable~~ to access the service. The issue occurred as a result of an erroneous change made by a third-party infrastructure provider. We were able to resolve the issue by escalating it to the provider. In addition, we are working to improve the reliability of the Box Sign service by enhancing our disaster recovery processes to prevent similar issues from occurring in the future.  ‌ 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
