# SIMbook Assignment Issue Update Dear Instructor, We would like to inform you that the SIMnet team has successfully corrected a regional issue with the SIMbook assignments. Between 1:30AM CST-11:00AM CST on 1/17/2014, your students may have had a blank blue screen on some of the SIMbook pages and/or the Let Me Try button may have been grayed out and unavailable. The issue reoccurred between 3:00AM CST on 1/19/2014 and 5:00AM CST on 1/20/2014. As of 5:00AM CST on 1/20/2014, the full functionality of the SIMbook assignments have been restored. Your students may need to clear their browser cache before loading the SIMbook assignments again. Our team will continue to closely monitor the system to ensure its performance. Should you or your students experience any issues, please contact our Customer Experience Group at . We apologize for any inconvenience this caused you and your students. Thank you again for your patience and continued support, The SIMnet Team --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
