Final Status: We’ve identified an issue that may have briefly prevented users from posting messages to Yammer. It was determined that a database migration caused several service components that facilitate message posting to become degraded. We halted the migration and confirmed that the service is now functioning as expected.
User Impact: Users may have been unable to create or update Yammer posts.
Scope of Impact: While we weren’t aware of any customer reports of impact, our monitoring indicated that many users were unable to post messages to Yammer for the duration of the incident.
