There is an issue currently affecting all courses regarding broken Tegrity links. When you click on the “Tegrity” link within a D2L course (under “Course Tools” or “A to Z” in the default navbar) you get re-routed to “etsu2.tegrity.com”, which promptly produces a “server not found” error. It should be going to “etsu.tegrity.com”. Tegrity has been contacted and will hopefully have a solution soon. Until then, you can fix the URL manually by removing the 2, and then re-loading the page.
