Over the last several weeks, IT Services staff have addressed several issues that, separately, were causing seriously degraded performance in AEM's Author environment. As of November 7, 2017, we believe that performance is largely back to normal in most cases — and even improved in some areas, compared to the period of time before the issues began in October.

We continue to monitor a small number of performance issues to determine whether they need further action now, or whether upgrade plans in the very near future are a more effective method of addressing them; the remaining issues are primarily affecting AEM administrative tasks for support staff, and are not expected to affect your daily work in the AEM Author environment. 

We will continue to track performance metrics to ensure that our mitigations remain effective, and will continue to work with vendor support at Adobe to address anything that arises.

The coming months will see further improvements as we return to our continual improvement practice, where we will be able to provide upgrades of various infrastructure components of the overall AEM system, as well as application version upgrades that will improve functionality. Further, the migration of all components of the AEM ecosystem to SFU's new Data Centre architecture will further improve reliability and resiliancy of not only AEM, but also the systems upon which AEM relies, and in turn the systems and sources of information which rely on AEM.  

AEM is a powerful but complex environment and we appreciate your patience as we worked through these issues.
