The CEDAR system is going through a major upgrade this Wednesday, January 24. It may be down much of the day as we upgrade both the CEDAR Workbench software, and the libraries like Java that support it.
Whenever the CEDAR system is not responding, you can visit our CEDAR status page, thanks to the StatusCake service. This will let you know if you are the only one, and if it's a planned outage, we'll put up a message indicating when we hope it will come back.
We appreciate your patience during this maintenance, and will update you on all the new capabilities as soon as the new version is up and running.
