Impact to Mason:
Some users reported issues accessing Blackboard.
Affected Services:
Class Collaborate (formerly Blackboard Collaborate Ultra), Blackboard Courses
ROOT CAUSE ANALYSIS
Cause:
A change was executed to enhance our DNS services to prevent DDoS events. However, this change was not successful which propagated incorrect DNS information across the internet.
Resolution:
The change was rolled back but DNS is a pull-based request and took time to propagate the correction across the internet.
Prevention:
Anthology/Blackboard is planning to re-execute the upgrade to our DNS services to prevent issues like the one experienced on 4/20. This change is targeted for Friday 4/28.
