UDOIT (the Universal Design Online content Inspection Tool) has scheduled a maintenance window.  

UDOIT provides automated accessibility testing for much of the content within ICON, including information on how to fix any accessibility problems it detects. 

During this scheduled maintenance window, UDOIT will be upgraded to version 2.3.5, and may experience brief periods of downtime.  New features of this version include detection of captions for Vimeo and Dailymotion videos in ICON courses, a new report summary, and multiple bug fixes.  This  scheduled maintenance window will not affect other aspects of ICON courses.
