Today’s DDoS attacks on key providers of core internet services have lead to performance issues with Crocodoc and the Box document-viewer in Canvas. Canvas itself was not affected, but Crocodoc and the Box document-viewer have been reported as being both currently unavailable due to the attack; this will be presented as the Unicycling Panda load screen with no document loading. As soon as Crocodoc and Box have a chance to recover, these documents should render and be viewable within Canvas once again.
If you encounter an issue with Crocodoc or the Box document-viewer, please use the following workarounds until the issue has been resolved:
