Panopto will be unavailable from 8pm–10pm on Thursday December 21st due to scheduled maintenance by the vendor. During this time media content in Panopto and the "Class Recordings" area of Canvas sites will be unavailable. Canvas and all other integrated tools will be available and unaffected by this maintenance.
