Is the Internet Archive IIIF v1 server down?
Our site has been successfully using the OpenSeadragon image viewer to view images hosted on the Internet Archive's IIIF server for the past few month, but starting around May 4, 2017 we are getting errors for a good percentage of the images displayed on our site. Initially, we were getting a 500 error, but today we are getting a 400 error. Is the server down? Has the Image API changed recently? Thanks!
