At 8:50 am Eastern on 6/12/2024 we were alerted about an issue with the Learning Management System affecting quizzes in the Tech Math – CML and Construction Drawings – CML courses. The development teams were able to pinpoint the cause and resolved the issue at 10:57 am.
So… what happened?
Tech Math – CML and Construction Drawings – CML both use questions that generate random variables that make each quiz and quiz attempt unique. When a student (or instructor) attempts a quiz, the system pulls the random variables needed for those question types. This morning, the number of concurrent random variable requests hit the limit that prevents overloading servers.
So… what did we do?
Because our LMS servers can automatically scale up and down as needed, the team was able to disable this parameter and the random variable function for these quizzes was restored.
We apologize for any interruptions and frustration caused by this incident. We will continue to monitor the LMS for issues, learn from incidents like this, and strive to deliver an online learning environment that performs flawlessly for your students and programs.
