Cox Cable ran several tests that might have affected access of some users to the UA WebAuth system. WebAuth is required to access several systems on campus, including UA email, D2L, and StudentLink. This means that the problems users are having are not a consequence of D2L malfunctioning--nonetheless they are not able to access D2L course sites. This might have affected a student's ability to complete activites in PreSession and Summer Session I course sites.
