Creative Cloud Web SDK Image Editor down?

We use the creative cloud web SDK image editor in our app that helps users design email templates. This morning our users reported that they're seeing an error. When accessing the image editor, this endpoint throws a 503 error when posted to with the appropriate information:

Another publicly available email template editor (Stripo) is also showing this issue when you try to edit an image, which leads us to believe it's an Adobe issue and not an issue with our setup. Here's the link to the Stripo editor: Stripo Demo — Html Email Template Builder

We know that Aviary has been deprecated recently, but the migration docs clearly state that migrating to the Creative Cloud is the preferred solution.

Anyone else seeing issues with this or any word from Adobe? We're not seeing any status updates and will need to use another editor if this isn't addressed in the next few days.
