Kaltura MediaSpace and the Kaltura Canvas integration experienced an outage on Wednesday morning 9/23 from 8:32-8:38 which Kaltura has resolved. This document describes the status of the ongoing issues with Kaltura:

Reported IssueStatus

Users may experience errors during or after upload such as Oops! Upload Failed, Oops! Uploaded bytes exceed file size, Oops! Internal database error, or Oops! Failed to match expected file size. This includes uploads from Kaltura Capture or lecture capture systems. 

Kaltura reports that upload performance has returned to normal on 9/24. If you experience an upload error you can try uploading again. More information is available in Kaltura - Known Issue - Upload results in Oops error.

Media processing times were extended - long duration or high resolution videos were taking 24 hours or longer to become available.

Kaltura reports that media processing times have returned to normal as of 9/17/20. Learn@UW-Madison continues to monitor. If you have media taking over 24 hours to process please contact the DoIT Help Desk.

Some media was experiencing slower playback (buffering or the spinning wheel) - especially media uploaded close to the time of attempted playback.

Kaltura implemented a solution on 9/21. Kaltura and Learn@UW-Madison continue to monitor.

Some caption files if downloaded are empty SRT caption files. The captions will still display on user's media. Some machine captions may be returned with timings off.

Kaltura is investigating the issue. Please see Kaltura - Known Issue - SRT caption files sometimes download as empty files and Kaltura - Known Issue - Some machine captions have timings that are off or not aligned for more information on the issues and workarounds.

If you experience issues with Kaltura the best approach is to retry after 20 minutes, focus on most immediate needs instead of uploading much of the semester’s content, and keeping videos under 6 minutes. That said, if issues continue and you need to share content immediately, you can use WebEx, Zoom, Canvas or Google Drive as an alternative. Regular updates about Kaltura MediaSpace at UW-Madison is available on outages.doit.wisc.edu. Kaltura also posts issues on their status page at status.kaltura.com.
