2. 2025年10月22日 18:35 UTCresolved

   This incident is resolved. A number of our third-party partner's Learning Management Systems (LMS) were down following an outage of AWS region us-east-1. We saw issues with partners like Blackboard and Canvas either unable to, or in limited capacity, able to receive grade posts for assignment submissions. This event did not have any direct impacts on the zyBooks system or it's ability to record student scores. Students and instructors can use the manual grade push options if their score does not appear to be synced with the LMS. https://support.zybooks.com/hc/en-us/articles/360042745653-How-does-Assignment-auto-submission-work#01JNPQMHVK46ZP9NVE5HEFSTGG
