Aug 2017: Blackboard Outages

Since Aug 18th, Blackboard has been impacted by multiple slowdowns throughout the day. In addition, there have been several instances where course copy operations were delayed for several hours.

Support staff are working to fix the underlying issue.

When individual nodes are offline, user traffic will automatically be routed to other available nodes. Single-node outages normally do not impact the entire system, but users on the node that goes offline may experience slowdowns or minor errors before their traffic is routed elsewhere.

As more nodes go offline, users are more likely to experience slowdowns and errors.

If all nodes are offline, Blackboard will become unusable.
