Vole 3D was down completely beginning after the maintenance window on Sunday. We recognized this problem this morning and have rebooted the Vole nodes. As the nodes come back up you should be able to connect to Vole 3D however, our SSL certificate has expired for vole 3D. This means you will still be able to connect to Vole 3D but your browser will warn you that the certificate has expired and you must confirm that you want to continue connecting.
Update 1/28/19 - Our certificate for Vole has been renewed. If you are still having any issues email us at firstname.lastname@example.org
