The issues with Unsplash appear to be resolved.

The Unsplash servers are recovering now and the search, browse, and shuffle functions in the media browser are loading images, but a bit slower than normal. We're keeping in touch with Unsplash and monitoring the situation.

Our integration with Unsplash is currently offline as they're experiencing issues. We're monitoring the problem and waiting for their servers to come back online.

Images already in use in your projects will remain visible, but while creating new projects you won't be able to browse the Unsplash servers for new images.
