Any of the following sites may be accessed when logging in to LabSim or accessing the LabSim courses and must be accessible through your web browser. Each of the sites listed can be added to a browsers allowed/trusted sites or as an exception on a firewall as necessary.
*Important note: The new LabSim 5 client uses cdn.testout.com. If cdn.testout.com is not allowed in the users browser or through a local or network firewall, the LabSim 5 login can fail. The symptom of this issue is a spinning circle of blue dots which does not go away.
