The Curative Analysis team in IT is tasked with finding the causes of significant IT issues that affect campus. In this news update, we draw your attention to some of the problems being investigated or issues handled recently.

Wireless Network:  A spike in CPU load on some wireless controllers has caused some users to occasionally receive a can’t connect to network prompt this semester. Networking staff have been working with the Aruba vendor and applied a patch at the end of September to resolve the issue. Networking staff continue to monitor the situation and follow-up with clients who have reported the problem.

Camp Network Outage:  A configuration change resulted in multiple devices located in the Camp building unable to connect to the network due to a loop in the building. Networking staff located and removed the loop, restoring access.

SharePoint Workflows:  A security update installed during regular maintenance caused an issue with workflows resuming in SharePoint. IT staff resolved the issue presented by the security update and manually ran any workflows that were affected.

PawPrint on Windows 10:  Mitigation of the Print Nightmare vulnerability resulted in several users unable to add printers on Windows 10 devices. IT staff disabled the mitigation to temporarily fix the problem and are waiting for a patch from the Microsoft vendor to fully resolve the issue.

Unable to Access Vault:  Some students were unable to access Investigation showed that authentication was paused while the database was backing up due to a scheduled job. IT staff changed the database backup schedule to ensure that it is not backing up during peak usage times. Vault and Mercury currently share a backup, and both systems are very large. During the Winter Break Data Center maintenance, IT staff will create separate backups for Vault and Mercury to prevent this issue from happening in the future.

Account Processing Portal:  An issue with a database server recently impacted the job processing portal for new account requests for consultants, suppliers, etc. A recurring issue causes the database to lose the permissions needed to do its job. IT staff have corrected the permissions, turned on auditing logs, and are currently working with the vendor, One Identity Manager (1IM) to identify a solution.

Android 12 on eduroam:  Devices could not connect to eduroam after updating to Android 12 due to the way certificates were interpreted. Networking staff updated the wireless setup profile to accommodate Android 12 devices.

Campus Network:  Users were unable to connect to the campus network and network resources after a configuration change during network maintenance on November 2. Networking staff rolled back the change to restore connectivity and rescheduled the change for December.
