### 2026-04-10 16:36 UTC: postmortem
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.
