March 16, 2015: Network outages

The campus network has experienced multiple brief interruptions in service which may have affected user access to BBLearn.

At least two outages were recorded, at approximately:

BBLearn Stability Issue

At 11:40 AM, one of our application nodes (bbapp3a) reporting abnormally heavy CPU use by the WIRIS Math Image Editor service. We took the node out of service to restart it, and had it back online by 12:00 PM.

The Math Image Editor feature will have been unavailable during this window.

When a single node goes out of service, users will automatically be routed to other nodes.
