University of Iowa students experienced troubles accessing Iowa Courses Online for several hours Sunday.

According to statements posted by Information Technology Services throughout the day, ICON was experiencing an issue where some of the users were unenrolled from courses listed on the site. At approximately 4:17 p.m., officials identified the problem and implemented a fix, yet did not have an exact time when students would be able to access the site.

As of 6:03 p.m., officials stated the problem would be fixed sometime after 9 p.m., and officials said most courses should be up before 7 p.m.

Officials from ITS were unable to provide the cause of the issue as of Sunday evening.
